- the through-hole 25 a is formed substantially into a U-shape open to the upper wall 22 when viewed from the front side (viewed in the X direction), and communicates with openings 22 a formed on the upper wall 22 .
- This configuration facilitates resin molding of the plug housing 20 including the land portion 25 provided with the through-hole 25 a only by use of upper and lower metal molds (upper mold 81 and lower mold 82 ) (refer to FIG. 6 ). In other words, the use of a slide core is not required so as to simplify the configuration of the molds used.

- the plug housing 20 includes the housing portion 24 for housing the wire 30 , the opening 24 a that communicates with the housing portion 24 in such a manner as to be open in the perpendicular direction (the Z direction) perpendicular to the wire extending direction (the X direction) in which the wire 30 extends so that the wire 30 housed in the housing portion 24 is exposed to the outside via the opening 24 a when viewed from the open direction (the Z direction), and the locking portion (the holding portion) 20 b for holding the wire 30 housed in the housing portion 24 .
- the housing portion 24 can receive, through the opening 24 a , the contact 50 connected to the board (the member to be connected) 60 .
- the contact 50 is received into the housing portion 24 from one side in the Z direction (from a bottom wall 27 of the plug housing 20 ).
- the contact 50 comes into contact with the wire 30 while the contact 50 is received by the housing portion 24 .
- the above-described configuration in which the contact 50 comes into contact with the wire 30 held by the plug housing 20 while the contact 50 is received by the housing portion 24 can decrease the thickness of the connector 10 in the Z direction.
- a mutual movement between the contact 50 and the wire 30 in contact with each other can be restricted so as to further improve the contact reliability.
- the plug housing 20 is provided with the through-hole (the wire introduction hole) 23 d by which the housing portion 24 communicates with the outside and through which the wire 30 is inserted so as to be housed in the housing portion 24 .
- This configuration facilitates the process of housing the wire 30 into the housing portion 24 .
- the through-hole 23 d is not open to other directions (the Z direction and Y direction) other than the X direction. That is, the through-hole 23 d is a hole which is closed when viewed in the X direction.
- the wire 30 is housed in the housing portion 24 in a state where a movement of the wire 30 in the other directions (the Z direction and Y direction) other than the X direction is restricted by the circumferential wall (the lateral wall portion 23 a ) of the through-hole 23 d .
- the wire 30 housed in the housing portion 24 is prevented from coming off the housing portion 24 in the directions other than the insertion direction (the X direction).
- the through-hole 25 a and the through-hole 23 e also have the same function to prevent the wire 30 from coming off the housing portion 24 in the directions other than the X direction.
- the respective through-holes are not required to be closed when viewed in the X direction. For example, even the through-holes provided with a notch smaller than the diameter of the wire 30 when viewed in the X direction, can achieve the similar effect as described above.
- the locking portion 20 b is a space defined by wall surfaces of the plug housing 20 and is provided with a through-hole on one of the wall surfaces surrounding the locking portion 20 b of the plug housing 20 in a manner such that the wire 30 is exposed to the outside when viewed in the penetrating direction (the Z direction in the present embodiment).
- the upper wall 22 is provided with an opening (open hole: through-hole) 22 b communicating with the locking portion 20 b and open in the Z direction so that the wire 30 is exposed to the outside when viewed in the Z direction.
- the locking portion 20 b is further provided with a through-hole (open hole) 27 a open in the Z direction on the bottom wall 27 on the opposite side of the opening (the through-hole) 22 b .
- the through-holes (the open holes: the opening 22 b and the through-hole 27 a ) are provided on both sides of the locking portion 20 b in the Z direction (on the wall surfaces opposite to each other among the wall surfaces surrounding the locking portion). This configuration allows the locking portion 20 b to penetrate the plug housing 20 on both sides in the Z direction so that the tip of the wire 30 inserted into the locking portion 20 b is exposed to the outside on both sides when viewed in the thickness direction of the plug housing 20 (the Z direction).
- the locking portion 20 b is thus a through-hole penetrating from one side to the other side of the plug housing 20 in the Z direction.
- the open holes provided on the wall surfaces surrounding the locking portion 20 b serve as viewing holes for confirming whether the wire 30 is inserted to the end of the plug housing 20 .
- the respective open holes are formed into a through-hole, the presence of the wire 30 can be confined through the holes more easily and reliably.
- the wire 30 is formed into an elongated cylindrical shape in a manner such that a conductive core 32 thereof is covered with an insulating covering member 31 .
- the wire 30 is inserted into the insertion hole 20 a in a state where part of the covering member 31 on the tip side of the wire 30 is removed so that the core 32 is exposed to the outside (refer to FIG. 8 ).
- the core 32 of the wire 30 in the present embodiment is composed of a solid wire (single-core wire) made of a single copper wire ( 4 ) 0 . 5 ).
- a tip portion 32 a of the core 32 inserted into the insertion hole 20 a is flattened and formed into a flattened portion 32 b having a plate shape while being inserted in the locking portion 20 b.
- the locking portion 20 b penetrates through the plug housing 20 from one side to the other side in the Z direction. Therefore, the tip portion 32 a of the core 32 can be flattened in such a manner as to insert a pressing portion 91 of a jig 90 for flattening from both sides in the Z direction (in the direction of arrow “a” in FIG. 9( a )).
- two jigs 90 for flattening are used to press the tip portion 32 a of the core 32 several times (two times in the present embodiment) while shifting the tip portions 32 a in the X direction so as to form the flattened portion 32 b with a plate shape.
- the flattened portion 32 b is formed in the state where the wire 30 is inserted into the plug housing 20 , so as to form a wired housing 40 in which the wire 30 is attached to the plug housing 20 .
- the wired housing 40 is formed by the following process.
- the wire 30 is inserted into the housing portion 24 of the plug housing 20 , and the tip portion 32 of the wire 30 is exposed to the outside through the through-hole (the locking portion 20 b , the opening 22 b and the through hole 27 a ) penetrating the plug housing 20 from one side to the other side in the Z direction.
- one of the pressing portions 91 formed on the jigs 90 is inserted into the through hole (the locking portion 20 b , the opening 22 b and the through hole 27 a ) from one side in the Z direction, and the other pressing portion 91 of the jigs 90 is inserted into the through hole from the other side.
- the tip portion 32 a of the wire 30 is then flattened by the respective pressing portions 91 , 91 so as to be provided with a first flattened portion 32 c .
- the through hole (the locking portion 20 b , the opening 22 b and the through hole 27 a ) penetrating in the Z direction enables the pressing portions 91 of the jigs 90 to be inserted from both side so as to flatten the tip portion 32 a of the wire 30 more stably.
- the wire 30 is shifted toward the insertion side in the X direction so that a part of the tip portion 32 a of the wire 30 not flattened is exposed to the outside through the through-hole.
- the part of the tip portion 32 a of the wire 30 not flattened is then flattened with the jigs 90 so as to be provided with a second flattened portion 32 d.
- the flattened portion 32 b is formed at the tip portion 32 a of the wire 30 .
- the flattened portion 32 b thus formed comes into contact (is locked) with a wall surface 23 f of the lateral wall portion 23 b when the wire 30 inserted in the plug housing 20 is shifted in the removing direction (on the removing side in the inserting-removing direction).
- the wire 30 can be attached to the plug housing 20 while being prevented from coming off the plug housing 20 .
- the wired housing 40 is thus formed.
- the process in which the wire 30 is shifted in the X direction, and the part of the tip portion 32 a of the wire 30 not flattened is exposed to the outside via the through-hole so as to be flattened with the jigs 90 may be repeated several times (two times or more). That is, the process of flattening the wire 30 may be repeated three times or more.
- the tip portion 32 a of the wire 30 may be flattened with the jigs 90 only once to be provided with the flattened portion 32 b .
- a side surface 32 f of the flattened portion 32 b is preferably held between both side surfaces 21 e , 21 e of a notch 21 c.
- the notch 21 c is formed at the longitudinal-direction-side circumferential wall 21 b on the opposite side of the upper wall 22 .
- a flat surface 32 e of the flattened portion 32 b comes into contact with a deep surface (the surface toward the upper wall 22 ) 21 d of the notch 21 c .
- This configuration prevents the wire 30 from rotating at the time of, for example, being attached to the contact 50 .
- the side surface 32 f of the flattened portion 32 b is held between the side surfaces 21 e , 21 e of the notch 21 c so as to prevent the wire 30 from rotating more reliably.
- the plug housing 20 includes the locking portion 20 b serving as the holding portion for holding the flattened portion 32 b of the wire 30 and also serving as a flattened-portion locking portion for locking the flattened portion 32 b .
- the wall surface 23 f of the lateral wall portion 23 b and the deep surface (the surface toward the upper wall 22 ) 21 d of the notch 21 c also serve as the flattened-portion locking portion.
- the plug housing 20 further includes a temporarily holding portion for temporarily holding the wire 30 housed in the housing portion 24 .
- the temporarily holding portion is a projection 21 f projecting from the mount surface 26 a of the mount portion 26 in the Z direction.
- FIG. 14 illustrates the projection 21 f formed on the inner side of the longitudinal-direction-side circumferential wall 21 b in the X direction (on the removing side in the inserting-removing direction of the wire 30 )
- the projection 21 f serving as the temporarily holding portion may be formed on the outer side of the longitudinal-direction-side circumferential wall 21 b in the X direction (on the inserting side in the inserting-removing direction of the wire 30 ), as shown in FIG. 15 .
- the projection 21 f is preferably provided with an inclined surface on the inner side thereof in the X direction (on the removing side in the inserting-removing direction of the wire 30 ), as shown in FIG. 14 and FIG. 15 .
- the wire 30 is guided by the inclined surface so as to be bent in the Z direction easily when the wire 30 is inserted.
- the contact 50 is formed in a manner such that a metal plate is subjected to metal processing (pressing) and includes a bottom wall 51 formed substantially into a rectangular shape elongated in the X direction.
- the bottom wall 51 is formed at both edge portions of the contact 50 in the X direction, and a connecting portion 52 is formed in the middle of the contact 50 in the X direction to connect the both bottom walls 51 to each other.
- the connecting portion 52 protrudes outward substantially into a trapezoid on both sides in the Y direction so as to have a wider width than the bottom walls 51 .
- the connecting portion 52 is thus formed substantially into an octagonal shape in the plan view.
- the connecting portion 52 may be formed into various shapes and may be a polygonal shape such as a rectangular shape or a circular shape.
- the bottom walls 51 or the connecting portion 52 can serve as an installation member connected (installed) to the board 60 .
- the bottom walls 51 can serve as an installation member connected (installed) to the board 60
- the connecting portion 52 can serve as an installation member connected (installed) to the board 60 .
- Both the bottom walls 51 and the connecting portion 52 can serve as an installation member connected (installed) to the board 60 .
- the bottom walls 51 and the connecting portion 52 are formed into a plate shape, and one surface 51 a of the respective bottom walls 51 and one surface 52 a of the connecting portion 52 serve as a movement regulation member 50 c described below.
- the respective other surfaces 51 b are installed to the board 60 .
- the connecting portion 52 serves as an installation member, the other surface 52 b is installed to the board 60 .
- the one surface 52 a of the connecting portion 52 includes an adhesion surface 52 c to which installation equipment (not shown in the drawing) such as a robot arm adheres.
- the adhesion surface 52 also serves as the movement regulation member 50 c described below.
- the contact 50 thus includes the installation member (at least one of bottom walls 51 and the connecting portion 52 ) installed and connected to the board (member to be connected) 60 .
- the movement regulation member 50 c is formed to include the installation member.
- the installation member includes the movement regulation member 50 c on one side and an installation surface on the other side installed to the board (the member to be connected) 60 .
- the movement regulation member 50 c is provided with the adhesion surface 52 c on one surface, which also serves as the movement regulation member 50 c.
- the adhesion surface 52 c can be used effectively to have another function.
- an additional member is not required for composing the movement regulation member 50 c , a decrease in size of the contact 50 can be achieved.
- the other surfaces 51 b of the bottom walls 51 or the other surface 52 b of the connecting portion 52 serve as an installation surface so as to eliminate a lead for installation.
- the contact 50 includes contact portions 53 coming into contact with and electrically connected to the core 32 of the wire 30 , and lock portions 54 for locking the wire 30 in a state where the wire 30 is in contact with the contact portions 53 .
- the state of locking the wire 30 includes a state of restricting a movement of the wire 30 on the contact 50 in the state where the wire 30 is in contact with the contact portions 53 .
- the state of locking includes not only a state of completely locking the wire 30 but also a state of generating resistance in the moving direction of the wire 30 so that the wire 30 is not easily moved. Therefore, in the present embodiment, the lock portions 54 correspond to a movement restriction member.
- the contact 50 further includes the movement regulation member 50 c for regulating a movement of the wire 30 in the Z direction in the state where the wire 30 is in contact with the contact portion 53 .
- the contact 50 including the movement regulation member 50 c can eliminate an additional member for preventing the contact state between the wire 30 and the contact portions 53 from being released because of a movement of the wire 30 on the contact 50 in the Z direction.
- the wire 30 can be prevented, only by use of the contact 50 , from coming off the contact 50 caused by excessive insertion of the wire 30 .
- the contact 50 includes the two (plural) contact portions 53 formed on the outer side of the respective bottom walls 51 in the X direction.
- Each of the contact portions 53 includes outer pieces 53 a extending upward on both sides of each bottom wall 51 in the Y direction, and elastically deformable inner pieces (contact pieces) 53 b integrated with the outer pieces 53 a .
- the respective tips of the inner pieces 53 b are provided with holding pieces (contact pieces) 53 c for holding the core 32 of the wire 30 .
- the holding pieces 53 c on both sides hold a wall surface 32 g of the core 32 of the wire 30 .
- the respective contact portions 53 of the present embodiment thus include the outer pieces 53 a as first side wall portions located on both sides thereof in the Y direction (the width direction) when viewed in the X direction, and the two holding pieces (at least one second side wall portion) 53 c located between the outer pieces 53 a.
- the two holding pieces 53 c (at least one second side wall portion) are formed in an elastically deformable manner in the Y direction.
- the second side wall portions of the present embodiment thus include the second side wall portions elastically deformable in the Y direction (width direction).
- the wire 30 is held on both sides in the Y direction (at least on one side in the Y direction) by the holding pieces 53 c elastically deformable in the Y direction.
- force applied to the wire 30 in the Y direction can be absorbed by elastic deformation of the holding pieces 53 c . Accordingly, force applied to the outer pieces (first wall portions) 53 a of the contact 50 can be prevented when the wire 30 is pulled in the Y direction so as to prevent the installation of the contact 50 on the board 60 from being released. In addition, removal of the wire 30 from the contact 50 can also be prevented.
- only one of the holding pieces 53 c may be formed in an elastically deformable manner in the Y direction (the width direction) so that the wire 30 is held at least on one side in the Y direction by the holding piece 53 c elastically deformable in the Y direction.
- the holding pieces (the contact pieces) 53 c are formed separately from locking pieces (lock pieces 54 a ) described below formed in the movement restriction member.
- the holding pieces (the contact pieces) 53 c and the locking pieces (the lock pieces 54 a ) are aligned in the X direction. Since the holding pieces (the contact pieces) 53 c and the locking pieces (the lock pieces 54 a ) are formed separately, the respective members can individually function to come into contact with the wire 30 and function to lock the wire 30 , so as to determine an appropriate shape for each member. Accordingly, the respective members can exhibit their own functions reliably.
- the contact portions 53 are formed to be open on the upper side (on the side opposite to the opening 24 ) as shown in FIG. 16( a ).
- the core 32 of the wire 30 comes into contact with the contact portions 53 so as to be electrically connected to each other. More particularly, the core 32 of the wire 30 is inserted into the opening of the respective contact portions 53 formed on the insertion side of the wire 30 (on the upper side in FIG. 16( a )), and the wall surface 32 g of the core 32 of the wire 30 is held by the holding pieces 53 c on both sides so that the core 32 of the wire 30 comes into contact with the contact portions 53 to be electrically connected to each other.
- the contact 50 further includes drop-off prevention portions 50 b for covering at least part of the wire 30 on the other side in the Z direction in the state where the wire 30 is in contact with the contact portions 53 (on the opening side in the state where the wire 30 is in contact with the contact portions 53 ).
- the drop-off prevention portions 50 b are formed in the contact pieces (the inner pieces 53 b ) of the contact portions 53 .
- the respective inner pieces (the contact pieces) 53 b protrude inward in the Y direction in a manner such that the gap between the respective inner pieces (the contact pieces) 53 b located on both sides in the Y direction is smaller than the diameter of the wire 30 .
- the respective inner pieces (the contact pieces) 53 b are curved greatly so as to protrude inward in the Y direction.
- the wire 30 can be prevented from moving in the direction opposite to the direction in which the wire 30 is attached (opposite to the direction in which the wire 30 is inserted into the contact 50 ) and prevented from coming off the contact 50 .
- the wire 30 is inserted into the contact 50 by climbing over the drop-off prevention portions 50 b protruding inward in the Y direction, a feeling of clicking can be ensured at the time of insertion of the wire 30 so that the connection of the wire 30 can be confirmed easily.
- the inner pieces (the contact pieces) 53 b are each formed into an arc shape protruding toward the other side in the Z direction (toward the opening 50 a : toward the side from which the wire 30 is inserted) when viewed in the X direction. Therefore, the contact portions 53 are provided, toward the other side in the Z direction (toward the opening 50 a : toward the side from which the wire 30 is inserted) when viewed in the X direction, with openings defined by the inner pieces of the inner pieces (the contact pieces) 53 b located on both sides in the Y direction and each having a width increasing toward the opening 50 a .
- the openings provided in the respective contact portions 53 and each having a width increasing toward the opening 50 a facilitates the insertion of the wire 30 into the contact 50 .
- the contact 50 also includes the two (plural) lock portions 54 formed on the inner side of the respective contact portions 53 in the X direction (on the inner sides of the respective bottom walls 51 in the X direction).
- the two lock portions 54 are provided symmetrically with the connecting portion 52 interposed therebetween when viewed in the Z direction.
- the respective lock portions 54 include the lock pieces 54 a for locking the wire 30 in the state where the wire 30 is in contact with the contact pieces 53 .
- the lock pieces 54 a are formed in a manner such that the metal plate used for the formation of the contact 50 is cut and raised upward.
- One end 54 b of the respective lock pieces 54 a is connected to the bottom wall portion 51 b serving as the movement regulation member, and the other end 54 c extends toward the wire 30 in contact with the contact portions 53 . More particularly, the other end 54 c is bent inward in the Y direction from the one end 54 b so as to form each lock piece 54 a .
- the lock pieces 54 a are elastically deformable in the Y direction (the width direction).
- the bent portion at the boundary between the one end 54 b and the other end 54 c is provided with a notched recess curved into an arc toward the movement regulation member 50 c .
- a recess increases the length in the Z direction at a portion where the wire 30 is locked (an edge 54 g in the present embodiment) in the respective lock pieces 54 a , compared with the length in the Z direction at the bent portion. Accordingly, a sufficient region in contact with the wire 30 (the length in the Z direction) can be ensured, and the other end 54 c can be elastically deformed more easily.
- the respective lock portions 54 include the locking pieces for locking the wire 30 being in contact with the contact pieces 53 , and the locking pieces include the lock pieces 54 a for holding the wire 30 being in contact with the contact pieces 53 . Since the lock pieces 54 a are elastically deformable in the Y direction (the width direction) as described above, the wire 30 can be inserted into the contact 50 in the Z direction due to the elastic deformation. Further, the wire 30 is pressed by elastic restoring force of the lock pieces 54 a in the state where the wire 30 is inserted into the contact 50 .

- the core 32 C composed of the stranded wire is covered with the insulating covering member 31 so as to form the wire 30 .
- the wire 30 is inserted into the insertion hole 30 a in the state where part of the covering member 31 on the tip side is removed to expose the core 32 C to the outside.
- the use of the straight stranded wire described above may cause the copper wires of the core 32 C to spread out in directions so that it is difficult to insert the wire into the insertion hole 20 a .
- the core 32 C is preferably subjected to pretreatment such as soldering.
- Such pretreatment facilitates the insertion of the core 32 C composed of the stranded wire into the insertion hole 20 a (the insertion recess 20 c , the through-hole 25 c , the locking portion 20 b ) of the plug housing 20 .
- the wire 30 includes the core 32 C composed of the stranded wire. Therefore, the wire 30 is more flexible than the wire 30 using the solid wire as a core so as to facilitate the laying operation.
- FIG. 29 illustrates a configuration in which the wire 30 is composed of a coaxial cable 32 D.
- an internal conductor 33 (core) composed of a stranded wire is covered with an insulator 34 , and an external conductor 35 formed on the outside of the insulator 34 is covered with the covering member 31 .
- the coaxial cable 32 D is flexible so as to facilitate the laying operation and prevent external leakage of electromagnetic waves.
- FIG. 29 illustrates the case where the internal conductor 33 (the core) is composed of the stranded wire
- the internal conductor 33 (the core) composed of a solid wire may be used.
- the contact 50 shown in FIG. 30 includes the drop-off prevention portions formed in the lock pieces (the locking pieces) 54 a of the lock portions (the movement restriction member) 54 for covering at least part of the wire 30 on the other side in the Z direction while being in contact with the contact portions 53 (toward the opening 50 a in the state where the wire 30 is in contact with the contact portions 53 ).
- the tips 54 f of the lock pieces (the locking pieces) 54 a are provided, on the opening 50 a side, with projections 54 i projecting in the Y direction and the X direction.
- the gap between the respective projections 54 i on both sides in the Y direction is smaller than the diameter of the wire 30 .
- the projections 54 i shown in FIG. 30 are each formed substantially into a trapezoid having a thickness decreasing toward the tip thereof when viewed from the side surface (when viewed in the Y direction). Therefore, inclined surfaces of the projections 54 i toward the opening 50 a can serve as a guide when the wire 30 is inserted so as to prevent the insertion of the wire 30 into the contact 50 from being blocked by the projections 54 i.
- the projections 54 i having such a configuration can prevent the wire 30 from moving in the direction opposite to the direction in which the wire 30 is attached (the direction in which the wire 30 is inserted) and prevent the wire 30 from coming off. Further, since the wire 30 is inserted into the contact 50 by climbing over the drop-off prevention portions protruding inward in the Y direction, a feeling of clicking can be ensured at the time of insertion of the wire 30 so that the connection of the wire 30 can be confirmed easily.
- the drop-off prevention portions are formed in the contact portions 53 and the lock portions (the movement restriction member) 54 to cover at least part of the wire 30 on the other side in the Z direction while being in contact with the contact portions 53 (toward the opening 50 a in the state where the wire 30 is in contact with the contact portions 53 ), the drop-off prevention portions may be formed only in the lock portions (the movement restriction member) 54 , instead of being formed in both the contact portions 53 and the lock portions (the movement restriction member) 54 .
- the contact 50 described above can also achieve substantially the same operations and effects as those in the first and second embodiments.
- the contact 50 shown in FIG. 30 has a configuration in which the locking portions of the lock pieces 54 a at which the wire 30 is locked (the edges 54 g ) and the holding pieces 53 c of the contact portions 53 are arranged approximately at even intervals in the X direction.
- the edges 54 g and the holding pieces 53 c are portions by which the insertion of the wire 30 into the contact 50 is blocked (portions at which the wire 30 is hardly inserted if greater force is not applied thereto than that applied to other portions in the contact) when the wire 30 is inserted into the contact 50 while two parts of the wire 30 on the outside of the contact 50 in the X direction are gripped.
- the blocking portions are arranged approximately at even intervals in the X direction in the contact 50 shown in FIG. 30 .
- the force applied to the wire 30 can be dispersed evenly in the X direction so as to be prevented from being partly applied to the wire 30 when the wire 30 is inserted into the contact 50 .
- the contact 50 shown in FIG. 31 has a configuration, as in the case of the contact shown in FIG. 30 , in which the drop-off prevention portions are formed in the lock pieces (the locking pieces) 54 a of the lock portions (the movement restriction member) 54 for covering at least part of the wire 30 on the other side in the Z direction while being in contact with the contact portions 53 (toward the opening 50 a in the state where the wire 30 is in contact with the contact portions 53 ).
- the contact 50 shown in FIG. 31 includes recesses 51 c formed on the bottom walls 51 serving as the installation member on the outer side in the X direction.
- the recesses 51 c are formed at the edges of the bottom walls 51 in the X direction. More particularly, the recesses 51 c are each formed in a manner such that a part of the edge of the bottom wall 51 in the X direction is notched into an arc shape.
- the recesses 51 c are each formed to penetrate in the Z direction so that the board (the member to be connected) 60 is exposed to the outside when viewed in the Z direction (viewed from one side of the installation member).
- the recesses 51 c may each be formed in a manner such that the entire edge of the bottom wall 51 in the X direction is notched into an arc shape, instead of being formed in a manner such that a part of the edge of the bottom wall 51 in the X direction is notched.
- the recesses may each be formed at an edge of the installation member in the Y direction.
- the recesses are not limited to the arc shape and may be any shapes, and the number of the recesses may also be determined as appropriate.
- the recesses 51 c can each serve as a soldering confirmation portion at which a solder fillet is formed.
- the recesses 51 c are formed on the bottom walls 51 c so that a state of solder wetting can be confirmed with the solder fillets formed at the recesses 51 c when the contact 50 is soldered onto the board (the member to be connected) 60 .
- the recesses 51 c thus contribute to easily determining whether the board (the member to be connected) 60 and the contact 50 are connected (installed) appropriately, and further improving the reliability of connection (installation) between the board (the member to be connected) 60 and the contact 50 .
- the connecting portion 52 may serve as the installation member where the soldering confirmation portion is formed.
- the soldering confirmation portion is not limited to the shape notched into a U-shape and may be various shapes such as a through-hole penetrating the bottom walls 51 in the thickness direction (the Z direction) formed adjacent to the edges of the bottom walls 51 . Further, the position and the number of the solder confirmation portion formed may be determined as appropriate. For example, the recesses or through holes may be formed at positions where soldering installation is performed, instead of the edges of the bottom walls 51 , so as to serve as the soldering confirmation portion.
- the contact 50 shown in FIG. 32 has a configuration in which the connecting portion 52 is formed into a rectangular shape, and the lock pieces (the locking pieces) 54 a of the respective lock portions (the movement restriction member) 54 are formed in a manner such that the tips 54 f extend outward in the X direction.
- the lock pieces 54 a of the two lock portions 54 having the shape described above also extend in opposite directions.
- the contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments.
- the contact 50 can also achieve substantially the same operations and effects as the contact 50 shown in FIG. 30 .
- the distance between the locking portions of the lock pieces 54 a at which the wire 30 is locked (the edges 54 g ) and the holding pieces 53 c of the contact portions 53 is smaller than that in the contact 50 shown in FIG. 30 .

- the contact 50 shown in FIG. 30 is provided with the four blocking portions by which the insertion of the wire 30 into the contact 50 is blocked.

- the contact 50 shown in FIG. 33 is provided with the two blocking portions closer to each other at which the insertion of the wire 30 into the contact 50 is blocked, in which the one ends 54 b of the lock portions 54 (the sides on which the wire 30 is not locked in the lock portions 54 ) are located on both sides of the contact 50 in the X direction.
- the contact 30 can more reliably be prevented from being bent upward (prevented from being inserted into the contact portions 53 located on the outer side in the X direction while the wire 30 is not inserted into the lock portions 54 located on the inner side in the X direction) when the wire 30 is inserted into the contact 50 while two parts of the wire 30 on the outside of the contact 50 in the X direction are gripped.
- the wire 30 can be shifted in the Y direction on both sides of the contact 50 in the X direction. Therefore, the wire 30 can be bent in the Y direction without decreasing the radius of curvature of the wire 30 adjacent to the contact 50 . Accordingly, the wire 30 can be bent in the Y direction at the position closer to the contact 50 so as to further expand the possibility of positioning of the contact 50 installed on the board (member to be connected) 60 (the possibility of arrangement of the contact 50 ).

In the following explanations, the longitudinal direction of a housing (wire extending direction: wire axial direction) is defined as X direction, the thickness direction of the housing (perpendicular direction perpendicular to the wire extending direction) is defined as Z direction, and the lateral direction of the housing (width direction) is defined as Y direction.
- In addition, the following several embodiments and modified examples include the same elements. Thus, the same elements are indicated by common reference numerals, and explanations thereof are not repeated.
- A
connector 10 according to the present embodiment includes acontact 50 connected to a board (member to be connected) 60, and a plug housing (housing) 20 in which awire 30 is housed and fixed (attached), as shown inFIG. 1 andFIG. 2 . Theconnector 10 electrically connects thewire 30 and theboard 60 in such a manner as to fit thewire 30 housed and fixed in the plug housing (the housing) 20 made of resin to thecontact 50 mounted on theboard 60 so as to bring thewire 30 into contact with thecontact 50. - As shown in
FIG. 3 toFIG. 5 , theplug housing 20 is formed substantially into a rectangular parallelepiped and includes acircumferential wall 21 and anupper wall 22. Thecircumferential wall 21 includes lateral-direction-sidecircumferential walls 21 a located on both sides in the width direction (the lateral direction: the Y direction) and elongated in the longitudinal direction (the axial direction of the wire 30: the X direction), and a longitudinal-direction-side circumferential wall 21 b located at one end in the longitudinal direction (the axial direction of the wire 30: the X direction) and elongated in the width direction (the lateral direction: the Y direction). Thecircumferential wall 21 has an opening formed substantially into a U-shape at the other end in the X direction. - The
plug housing 20 further includes ahousing portion 24 communicating with anopening 24 a provided at least on one surface (on the upper side inFIG. 4( b): the Z direction: the perpendicular direction). Thewire 30 is housed in thehousing portion 24. According to the present embodiment, the opening 24 a communicates with thehousing portion 24 in such a manner as to be open in the Z direction (the perpendicular direction) perpendicular to the X direction (the wire extending direction in which thewire 30 extends). Thewire 30 housed and held in thehousing portion 24 is exposed to the outside via theopening 24 a when viewed in the open direction of the opening 24 a (the Z direction). Thus, thewire 30 housed in thehousing portion 24 can be visually recognized through the opening 24 a. In the present embodiment, thehousing portion 24 is defined by the lateral-direction-sidecircumferential walls lateral wall portions circumferential walls - The
housing portion 24 is provided in the middle thereof with aland portion 25. Theland portion 25 is fixed to the lateral-direction-sidecircumferential walls wall portions 23 c. Thus, thehousing portion 24 is divided into two regions by theland portion 25 and the connectingwall portions - The
land portion 25 is provided with a through-hole 25 a penetrating in the X direction so that thewire 30 passes therethrough. In the present embodiment, the through-hole 25 a is formed substantially into a U-shape open to theupper wall 22 when viewed from the front side (viewed in the X direction), and communicates withopenings 22 a formed on theupper wall 22. This configuration facilitates resin molding of theplug housing 20 including theland portion 25 provided with the through-hole 25 a only by use of upper and lower metal molds (upper mold 81 and lower mold 82) (refer toFIG. 6 ). In other words, the use of a slide core is not required so as to simplify the configuration of the molds used. - The
housing portion 24 is further provided, on both sides of theland portion 25 in thehousing portion 24, withmount portions 26 extending in the X direction for mounting thewire 30 and including mount surfaces 26 a on which thewire 30 is mounted. Themount portions 26 provided in theplug housing 20 can hold thewire 30 more stably. Note that, although the present invention exemplifies the flat mount surfaces 26 a as shown in the drawings such asFIG. 5 , the mount surfaces 26 a of themount portions 26 are each preferably formed into a shape conforming to the surface of thewire 30 as shown inFIG. 7 . In particular, when thewire 30 has an elongated cylindrical shape as exemplified in the present embodiment, the mount surfaces 26 a are each preferably formed into a concave shape recessed in the middle in the Y direction so as to come into contact and conform with the surface of thewire 30 having the circumferential surface of the cylindrical shape. Accordingly, thewire 30 can be mounted on themount portions 26 more stably. - The
lateral wall portions plug housing 20 are provided, on the respective outer sides thereof in the X direction, with aninsertion recess 20 c through which thewire 30 is inserted into theplug housing 20 and a locking portion (holding portion for holding the tip of the wire 30) 20 b for locking the tip of thewire 30 inserted into theplug housing 20. - The
insertion recess 20 c has an opening on the outer side in the X direction and communicates, on the inner side in the X direction, with a through-hole (wire introduction hole) 23 d of thelateral wall portion 23 a. Thewire 30 is inserted through the opening on the outer side in the X direction. - The locking
portion 20 b communicates, on the inner side in the X direction, with a through-hole 23 e of thelateral wall portion 23 b and is provided with a space on the outer side in the X direction defined by the longitudinal-direction-side circumferential wall 21 b. - According to the present invention, an
insertion hole 20 a is composed of theinsertion recess 20 c, the through-hole 23 d of thelateral wall portion 23 a, themount surface 26 a of themount portion 26, the through-hole 25 a of theland portion 25, themount surface 26 a of themount portion 26, the through-hole 23 e of thelateral wall portion 23 b, and the lockingportion 20 b, through which thewire 30 is inserted into the plug housing. - As described above, the
plug housing 20 includes thehousing portion 24 for housing thewire 30, the opening 24 a that communicates with thehousing portion 24 in such a manner as to be open in the perpendicular direction (the Z direction) perpendicular to the wire extending direction (the X direction) in which thewire 30 extends so that thewire 30 housed in thehousing portion 24 is exposed to the outside via theopening 24 a when viewed from the open direction (the Z direction), and the locking portion (the holding portion) 20 b for holding thewire 30 housed in thehousing portion 24. Thehousing portion 24 can receive, through the opening 24 a, thecontact 50 connected to the board (the member to be connected) 60. Thecontact 50 is received into thehousing portion 24 from one side in the Z direction (from abottom wall 27 of the plug housing 20). Thecontact 50 comes into contact with thewire 30 while thecontact 50 is received by thehousing portion 24. The above-described configuration in which thecontact 50 comes into contact with thewire 30 held by theplug housing 20 while thecontact 50 is received by thehousing portion 24, can decrease the thickness of theconnector 10 in the Z direction. In addition, a mutual movement between thecontact 50 and thewire 30 in contact with each other can be restricted so as to further improve the contact reliability. - The
plug housing 20 is provided with the through-hole (the wire introduction hole) 23 d by which thehousing portion 24 communicates with the outside and through which thewire 30 is inserted so as to be housed in thehousing portion 24. This configuration facilitates the process of housing thewire 30 into thehousing portion 24. The through-hole 23 d is not open to other directions (the Z direction and Y direction) other than the X direction. That is, the through-hole 23 d is a hole which is closed when viewed in the X direction. Accordingly, thewire 30 is housed in thehousing portion 24 in a state where a movement of thewire 30 in the other directions (the Z direction and Y direction) other than the X direction is restricted by the circumferential wall (thelateral wall portion 23 a) of the through-hole 23 d. Thus, thewire 30 housed in thehousing portion 24 is prevented from coming off thehousing portion 24 in the directions other than the insertion direction (the X direction). The through-hole 25 a and the through-hole 23 e also have the same function to prevent thewire 30 from coming off thehousing portion 24 in the directions other than the X direction. Note that the respective through-holes are not required to be closed when viewed in the X direction. For example, even the through-holes provided with a notch smaller than the diameter of thewire 30 when viewed in the X direction, can achieve the similar effect as described above. - In the present embodiment, the locking
portion 20 b is a space defined by wall surfaces of theplug housing 20 and is provided with a through-hole on one of the wall surfaces surrounding the lockingportion 20 b of theplug housing 20 in a manner such that thewire 30 is exposed to the outside when viewed in the penetrating direction (the Z direction in the present embodiment). - More particularly, the
upper wall 22 is provided with an opening (open hole: through-hole) 22 b communicating with the lockingportion 20 b and open in the Z direction so that thewire 30 is exposed to the outside when viewed in the Z direction. - The locking
portion 20 b is further provided with a through-hole (open hole) 27 a open in the Z direction on thebottom wall 27 on the opposite side of the opening (the through-hole) 22 b. Thus, the through-holes (the open holes: the opening 22 b and the through-hole 27 a) are provided on both sides of the lockingportion 20 b in the Z direction (on the wall surfaces opposite to each other among the wall surfaces surrounding the locking portion). This configuration allows the lockingportion 20 b to penetrate theplug housing 20 on both sides in the Z direction so that the tip of thewire 30 inserted into the lockingportion 20 b is exposed to the outside on both sides when viewed in the thickness direction of the plug housing 20 (the Z direction). The lockingportion 20 b is thus a through-hole penetrating from one side to the other side of theplug housing 20 in the Z direction. The open holes provided on the wall surfaces surrounding the lockingportion 20 b serve as viewing holes for confirming whether thewire 30 is inserted to the end of theplug housing 20. Particularly, when the respective open holes are formed into a through-hole, the presence of thewire 30 can be confined through the holes more easily and reliably. - The
wire 30 is formed into an elongated cylindrical shape in a manner such that aconductive core 32 thereof is covered with an insulatingcovering member 31. Thewire 30 is inserted into theinsertion hole 20 a in a state where part of the coveringmember 31 on the tip side of thewire 30 is removed so that thecore 32 is exposed to the outside (refer toFIG. 8 ). Here, thecore 32 of thewire 30 in the present embodiment is composed of a solid wire (single-core wire) made of a single copper wire (4) 0.5). - A
tip portion 32 a of the core 32 inserted into theinsertion hole 20 a is flattened and formed into a flattenedportion 32 b having a plate shape while being inserted in the lockingportion 20 b. - The locking
portion 20 b penetrates through theplug housing 20 from one side to the other side in the Z direction. Therefore, thetip portion 32 a of the core 32 can be flattened in such a manner as to insert apressing portion 91 of ajig 90 for flattening from both sides in the Z direction (in the direction of arrow “a” inFIG. 9( a)). - In the present embodiment, two
jigs 90 for flattening are used to press thetip portion 32 a of the core 32 several times (two times in the present embodiment) while shifting thetip portions 32 a in the X direction so as to form the flattenedportion 32 b with a plate shape. - As described above, the flattened
portion 32 b is formed in the state where thewire 30 is inserted into theplug housing 20, so as to form awired housing 40 in which thewire 30 is attached to theplug housing 20. - More particularly, the
wired housing 40 is formed by the following process. - First, the
wire 30 is inserted into thehousing portion 24 of theplug housing 20, and thetip portion 32 of thewire 30 is exposed to the outside through the through-hole (the lockingportion 20 b, theopening 22 b and the throughhole 27 a) penetrating theplug housing 20 from one side to the other side in the Z direction. - Next, one of the
pressing portions 91 formed on thejigs 90 is inserted into the through hole (the lockingportion 20 b, theopening 22 b and the throughhole 27 a) from one side in the Z direction, and the other pressingportion 91 of thejigs 90 is inserted into the through hole from the other side. Thetip portion 32 a of thewire 30 is then flattened by the respectivepressing portions portion 32 c. Thus, the through hole (the lockingportion 20 b, theopening 22 b and the throughhole 27 a) penetrating in the Z direction enables thepressing portions 91 of thejigs 90 to be inserted from both side so as to flatten thetip portion 32 a of thewire 30 more stably. - Thereafter, the
wire 30 is shifted toward the insertion side in the X direction so that a part of thetip portion 32 a of thewire 30 not flattened is exposed to the outside through the through-hole. The part of thetip portion 32 a of thewire 30 not flattened is then flattened with thejigs 90 so as to be provided with a second flattenedportion 32 d. - Accordingly, the flattened
portion 32 b is formed at thetip portion 32 a of thewire 30. The flattenedportion 32 b thus formed comes into contact (is locked) with awall surface 23 f of thelateral wall portion 23 b when thewire 30 inserted in theplug housing 20 is shifted in the removing direction (on the removing side in the inserting-removing direction). As a result, thewire 30 can be attached to theplug housing 20 while being prevented from coming off theplug housing 20. - The
wired housing 40 is thus formed. - Here, the process in which the
wire 30 is shifted in the X direction, and the part of thetip portion 32 a of thewire 30 not flattened is exposed to the outside via the through-hole so as to be flattened with thejigs 90, may be repeated several times (two times or more). That is, the process of flattening thewire 30 may be repeated three times or more. Alternately, thetip portion 32 a of thewire 30 may be flattened with thejigs 90 only once to be provided with the flattenedportion 32 b. In such a case, as described below, aside surface 32 f of the flattenedportion 32 b is preferably held between both side surfaces 21 e, 21 e of anotch 21 c. - In the present embodiment, the
notch 21 c is formed at the longitudinal-direction-side circumferential wall 21 b on the opposite side of theupper wall 22. Aflat surface 32 e of the flattenedportion 32 b comes into contact with a deep surface (the surface toward the upper wall 22) 21 d of thenotch 21 c. This configuration prevents thewire 30 from rotating at the time of, for example, being attached to thecontact 50. Theside surface 32 f of the flattenedportion 32 b is held between the side surfaces 21 e, 21 e of thenotch 21 c so as to prevent thewire 30 from rotating more reliably. - As described above, the
plug housing 20 includes the lockingportion 20 b serving as the holding portion for holding the flattenedportion 32 b of thewire 30 and also serving as a flattened-portion locking portion for locking the flattenedportion 32 b. In the present embodiment, thewall surface 23 f of thelateral wall portion 23 b and the deep surface (the surface toward the upper wall 22) 21 d of thenotch 21 c also serve as the flattened-portion locking portion. - In the present embodiment, as shown in
FIG. 14 , theplug housing 20 further includes a temporarily holding portion for temporarily holding thewire 30 housed in thehousing portion 24. - More particularly, the temporarily holding portion is a
projection 21 f projecting from themount surface 26 a of themount portion 26 in the Z direction. Once thewire 30 comes into contact with theprojection 21 f, thewire 30 is bent in the Z direction. Thus, thewire 30 bent in the Z direction due to theprojection 21 f is temporarily held in theplug housing 20. - Although
FIG. 14 illustrates theprojection 21 f formed on the inner side of the longitudinal-direction-side circumferential wall 21 b in the X direction (on the removing side in the inserting-removing direction of the wire 30), theprojection 21 f serving as the temporarily holding portion may be formed on the outer side of the longitudinal-direction-side circumferential wall 21 b in the X direction (on the inserting side in the inserting-removing direction of the wire 30), as shown inFIG. 15 . Theprojection 21 f is preferably provided with an inclined surface on the inner side thereof in the X direction (on the removing side in the inserting-removing direction of the wire 30), as shown inFIG. 14 andFIG. 15 . Thewire 30 is guided by the inclined surface so as to be bent in the Z direction easily when thewire 30 is inserted. - The
contact 50 is formed in a manner such that a metal plate is subjected to metal processing (pressing) and includes abottom wall 51 formed substantially into a rectangular shape elongated in the X direction. In the present embodiment, thebottom wall 51 is formed at both edge portions of thecontact 50 in the X direction, and a connectingportion 52 is formed in the middle of thecontact 50 in the X direction to connect the bothbottom walls 51 to each other. In the present embodiment, the connectingportion 52 protrudes outward substantially into a trapezoid on both sides in the Y direction so as to have a wider width than thebottom walls 51. The connectingportion 52 is thus formed substantially into an octagonal shape in the plan view. Note that the connectingportion 52 may be formed into various shapes and may be a polygonal shape such as a rectangular shape or a circular shape. - The
bottom walls 51 or the connectingportion 52 can serve as an installation member connected (installed) to theboard 60. Thebottom walls 51 can serve as an installation member connected (installed) to theboard 60, or the connectingportion 52 can serve as an installation member connected (installed) to theboard 60. Both thebottom walls 51 and the connectingportion 52 can serve as an installation member connected (installed) to theboard 60. - The
bottom walls 51 and the connectingportion 52 are formed into a plate shape, and onesurface 51 a of therespective bottom walls 51 and onesurface 52 a of the connectingportion 52 serve as amovement regulation member 50 c described below. When thebottom walls 51 serve as an installation member, the respectiveother surfaces 51 b are installed to theboard 60. When the connectingportion 52 serves as an installation member, theother surface 52 b is installed to theboard 60. - Further, in the present embodiment, the one
surface 52 a of the connectingportion 52 includes anadhesion surface 52 c to which installation equipment (not shown in the drawing) such as a robot arm adheres. Theadhesion surface 52 also serves as themovement regulation member 50 c described below. - The
contact 50 thus includes the installation member (at least one ofbottom walls 51 and the connecting portion 52) installed and connected to the board (member to be connected) 60. Themovement regulation member 50 c is formed to include the installation member. - The installation member includes the
movement regulation member 50 c on one side and an installation surface on the other side installed to the board (the member to be connected) 60. - The
movement regulation member 50 c is provided with theadhesion surface 52 c on one surface, which also serves as themovement regulation member 50 c. - Accordingly, the
adhesion surface 52 c can be used effectively to have another function. In addition, since an additional member is not required for composing themovement regulation member 50 c, a decrease in size of thecontact 50 can be achieved. Further, theother surfaces 51 b of thebottom walls 51 or theother surface 52 b of the connectingportion 52 serve as an installation surface so as to eliminate a lead for installation. - The
contact 50 includescontact portions 53 coming into contact with and electrically connected to thecore 32 of thewire 30, and lockportions 54 for locking thewire 30 in a state where thewire 30 is in contact with thecontact portions 53. Here, the state of locking thewire 30 includes a state of restricting a movement of thewire 30 on thecontact 50 in the state where thewire 30 is in contact with thecontact portions 53. In other words, the state of locking includes not only a state of completely locking thewire 30 but also a state of generating resistance in the moving direction of thewire 30 so that thewire 30 is not easily moved. Therefore, in the present embodiment, thelock portions 54 correspond to a movement restriction member. - The
contact 50 further includes themovement regulation member 50 c for regulating a movement of thewire 30 in the Z direction in the state where thewire 30 is in contact with thecontact portion 53. As described above, not only the connectingportion 52 but also thebottom walls 51 serve as themovement regulation member 50 c. Therefore, thecontact 50 including themovement regulation member 50 c can eliminate an additional member for preventing the contact state between thewire 30 and thecontact portions 53 from being released because of a movement of thewire 30 on thecontact 50 in the Z direction. Thus, thewire 30 can be prevented, only by use of thecontact 50, from coming off thecontact 50 caused by excessive insertion of thewire 30. - In the present embodiment, the
contact 50 includes the two (plural)contact portions 53 formed on the outer side of therespective bottom walls 51 in the X direction. Each of thecontact portions 53 includesouter pieces 53 a extending upward on both sides of eachbottom wall 51 in the Y direction, and elastically deformable inner pieces (contact pieces) 53 b integrated with theouter pieces 53 a. The respective tips of theinner pieces 53 b are provided with holding pieces (contact pieces) 53 c for holding thecore 32 of thewire 30. The holdingpieces 53 c on both sides hold awall surface 32 g of thecore 32 of thewire 30. - The
respective contact portions 53 of the present embodiment thus include theouter pieces 53 a as first side wall portions located on both sides thereof in the Y direction (the width direction) when viewed in the X direction, and the two holding pieces (at least one second side wall portion) 53 c located between theouter pieces 53 a. - The two holding
pieces 53 c (at least one second side wall portion) are formed in an elastically deformable manner in the Y direction. The second side wall portions of the present embodiment thus include the second side wall portions elastically deformable in the Y direction (width direction). - The
wire 30 is held on both sides in the Y direction (at least on one side in the Y direction) by the holdingpieces 53 c elastically deformable in the Y direction. - Therefore, force applied to the
wire 30 in the Y direction can be absorbed by elastic deformation of the holdingpieces 53 c. Accordingly, force applied to the outer pieces (first wall portions) 53 a of thecontact 50 can be prevented when thewire 30 is pulled in the Y direction so as to prevent the installation of thecontact 50 on theboard 60 from being released. In addition, removal of thewire 30 from thecontact 50 can also be prevented. - Alternatively, only one of the holding
pieces 53 c may be formed in an elastically deformable manner in the Y direction (the width direction) so that thewire 30 is held at least on one side in the Y direction by the holdingpiece 53 c elastically deformable in the Y direction. - In the present embodiment, the holding pieces (the contact pieces) 53 c are formed separately from locking pieces (lock
pieces 54 a) described below formed in the movement restriction member. The holding pieces (the contact pieces) 53 c and the locking pieces (thelock pieces 54 a) are aligned in the X direction. Since the holding pieces (the contact pieces) 53 c and the locking pieces (thelock pieces 54 a) are formed separately, the respective members can individually function to come into contact with thewire 30 and function to lock thewire 30, so as to determine an appropriate shape for each member. Accordingly, the respective members can exhibit their own functions reliably. - The
contact portions 53 are formed to be open on the upper side (on the side opposite to the opening 24) as shown inFIG. 16( a). In the present embodiment, when thewire 30 is moved in the direction perpendicular to the axial direction (the extending direction) of thewire 30 and inserted into thecontact portions 53, thecore 32 of thewire 30 comes into contact with thecontact portions 53 so as to be electrically connected to each other. More particularly, thecore 32 of thewire 30 is inserted into the opening of therespective contact portions 53 formed on the insertion side of the wire 30 (on the upper side inFIG. 16( a)), and the wall surface 32 g of thecore 32 of thewire 30 is held by the holdingpieces 53 c on both sides so that thecore 32 of thewire 30 comes into contact with thecontact portions 53 to be electrically connected to each other. - Thus, in the present embodiment, when the
wire 30 not in contact with thecontact portions 53 is moved to one side in the Z direction (in the direction from the opening to the bottom walls 51), thewire 30 comes into contact with thecontact portions 53. - The
contact 50 further includes drop-off prevention portions 50 b for covering at least part of thewire 30 on the other side in the Z direction in the state where thewire 30 is in contact with the contact portions 53 (on the opening side in the state where thewire 30 is in contact with the contact portions 53). - In the present embodiment, the drop-
off prevention portions 50 b are formed in the contact pieces (theinner pieces 53 b) of thecontact portions 53. - More particularly, the respective inner pieces (the contact pieces) 53 b protrude inward in the Y direction in a manner such that the gap between the respective inner pieces (the contact pieces) 53 b located on both sides in the Y direction is smaller than the diameter of the
wire 30. In the present embodiment, the respective inner pieces (the contact pieces) 53 b are curved greatly so as to protrude inward in the Y direction. - Accordingly, the
wire 30 can be prevented from moving in the direction opposite to the direction in which thewire 30 is attached (opposite to the direction in which thewire 30 is inserted into the contact 50) and prevented from coming off thecontact 50. In addition, since thewire 30 is inserted into thecontact 50 by climbing over the drop-off prevention portions 50 b protruding inward in the Y direction, a feeling of clicking can be ensured at the time of insertion of thewire 30 so that the connection of thewire 30 can be confirmed easily. - The inner pieces (the contact pieces) 53 b are each formed into an arc shape protruding toward the other side in the Z direction (toward the opening 50 a: toward the side from which the
wire 30 is inserted) when viewed in the X direction. Therefore, thecontact portions 53 are provided, toward the other side in the Z direction (toward the opening 50 a: toward the side from which thewire 30 is inserted) when viewed in the X direction, with openings defined by the inner pieces of the inner pieces (the contact pieces) 53 b located on both sides in the Y direction and each having a width increasing toward the opening 50 a. The openings provided in therespective contact portions 53 and each having a width increasing toward the opening 50 a, facilitates the insertion of thewire 30 into thecontact 50. - The
contact 50 also includes the two (plural)lock portions 54 formed on the inner side of therespective contact portions 53 in the X direction (on the inner sides of therespective bottom walls 51 in the X direction). The twolock portions 54 are provided symmetrically with the connectingportion 52 interposed therebetween when viewed in the Z direction. - The
respective lock portions 54 include thelock pieces 54 a for locking thewire 30 in the state where thewire 30 is in contact with thecontact pieces 53. Thelock pieces 54 a are formed in a manner such that the metal plate used for the formation of thecontact 50 is cut and raised upward. Oneend 54 b of therespective lock pieces 54 a is connected to thebottom wall portion 51 b serving as the movement regulation member, and theother end 54 c extends toward thewire 30 in contact with thecontact portions 53. More particularly, theother end 54 c is bent inward in the Y direction from the oneend 54 b so as to form eachlock piece 54 a. Thus, thelock pieces 54 a are elastically deformable in the Y direction (the width direction). - Further, the bent portion at the boundary between the one
end 54 b and theother end 54 c is provided with a notched recess curved into an arc toward themovement regulation member 50 c. Such a recess increases the length in the Z direction at a portion where thewire 30 is locked (anedge 54 g in the present embodiment) in therespective lock pieces 54 a, compared with the length in the Z direction at the bent portion. Accordingly, a sufficient region in contact with the wire 30 (the length in the Z direction) can be ensured, and theother end 54 c can be elastically deformed more easily. - As described above, the
respective lock portions 54 include the locking pieces for locking thewire 30 being in contact with thecontact pieces 53, and the locking pieces include thelock pieces 54 a for holding thewire 30 being in contact with thecontact pieces 53. Since thelock pieces 54 a are elastically deformable in the Y direction (the width direction) as described above, thewire 30 can be inserted into thecontact 50 in the Z direction due to the elastic deformation. Further, thewire 30 is pressed by elastic restoring force of thelock pieces 54 a in the state where thewire 30 is inserted into thecontact 50. Thus, thelock pieces 54 a elastically deformable in the Y direction (the width direction) formed in thelock portions 54 can facilitate the insertion of thewire 30 into thecontact 50 and also lock the insertedwire 30 more reliably (restrict a movement of thewire 30 in the X direction). - The configuration of the locking pieces is not limited to the lock pieces and may be any kinds of configurations. For example, the locking pieces may pierce the wire so as to lock the wire, may engage with the wire or may increase friction at the contact portions between the locking pieces and the wire. These means may be combined together.
- The
lock portions 54 each include a first lock piece (a first locking piece) 54 d and a second lock piece (a second locking piece) 54 e facing each other with thewire 30 interposed therebetween when viewed in the X direction. - As shown in
FIG. 17 , themovement regulation member 50 c is located between a locking portion of thefirst lock piece 54 d (theedge 54 g in the present embodiment) and a locking portion of thesecond lock piece 54 e (theedge 54 g in the present embodiment), when viewed in the Z direction. - In other words, the width of the
movement regulation member 50 c in the Y direction at a portion corresponding to the locking portions (theedges 54 g) is greater than the distance in the Y direction between the locking portion of thefirst lock piece 54 d and the locking portion of thesecond lock piece 54 e in eachlock piece 54. - Thus, the movement of the
wire 30 in the insertion direction at the portions locked by thelock portions 54 is regulated by the movement regulation member so that the locked state of thewire 30 locked by thelock portions 54 can be prevented from being released more reliably. - In the present embodiment, the
lock pieces 54 a extend in such a manner as to make an acute angle with thewire 30 being in contact with the contact portions 53 (acute angle to the wire extending direction) when viewed in the Z direction. In other words, the distance between therespective lock pieces 54 a and thewire 30 gradually decreases from oneend 54 b to theother end 54 c, when viewed in the Z direction. - Since the
lock portions 54 each include the first lock piece 43 d and thesecond lock piece 54 e as thelock pieces 54 a, the respective sets of thelock pieces 54 a are tapered having a width gradually decreasing toward atip 54 f (toward the inside in the X direction) in the plan view. - The
respective lock portions 54 are also open on the upper side (on the side opposite to the opening 24) as shown inFIG. 16( a). Thewire 30 is moved in the direction perpendicular to the axial direction (the extending direction) of thewire 30 so as to be inserted between thefirst lock pieces 54 d and thesecond lock pieces 54 e from the respective openings. - The distance in the Y direction between the locking portion of the
first lock piece 54 d and the locking portion of thesecond lock piece 54 e in eachlock portion 54 is preferably smaller than the diameter of the wire 30 (the core 32) held between thelock pieces 54 a. Thefirst lock piece 54 d and thesecond lock piece 54 e are elastically deformed outward in the Y direction when thewire 30 is inserted into thecontact 50. Thefirst lock piece 54 d and thesecond lock piece 54 e then press thewire 30 by elastic restoring force applied inward in the Y direction in the state where thewire 30 is inserted into thecontact 50. This configuration facilitates the insertion of thewire 30 into thecontact 50 and also locks the insertedwire 30 more reliably (restricts a movement of thewire 30 in the X direction). - In the present embodiment, the
lock pieces 54 a of the twolock portions 54 extend in opposite directions. - The explanation thereof is made in more detail with reference to
FIG. 16( a). Thelock pieces 54 a in one lock portion 54 (the lock portion on the lower-left side) extend from the one ends 54 b to the other ends 54 c in the upper-right direction, and thelock pieces 54 a in the other lock portion 54 (the lock portion on the upper-right side) extend from the one ends 54 b to the other ends 54 c in the lower-left direction. - Thus, the plural lock portions (the movement restriction member) 54 according to the present embodiment include at least one lock portion (the movement restriction member) 54 having the lock pieces (the locking pieces) 54 a in which the other ends 54 c are located on one side in the X direction while the one ends 54 b are located on the other side, and at least one lock portion (the movement restriction member) 54 having the lock pieces (the locking pieces) 54 a in which the other ends 54 c are located on the other side in the X direction while the one ends 54 c are located on the one side.
- Therefore, a movement of the
wire 30 to both sides in the X direction can be restricted more reliably. More particularly, when thewire 30 being in contact with (inserted in) thecontact 50 is intended to be shifted to the upper-right side inFIG. 16( a), thewire 30 is stuck mainly at the lock pieces (the locking pieces) 54 a of thelock portion 54 located on the upper-right side so as to be prevented from moving to the upper-right side inFIG. 16( a). When thewire 30 is intended to be shifted to the lower-left side inFIG. 16( b), thewire 30 is stuck mainly at the lock pieces (the locking pieces) 54 a of thelock portion 54 located on the lower-left side so as to be prevented from moving to the lower-left side inFIG. 16( b). - Further, the wall surface 32 g of the
core 32 is held by thetips 54 f on both sides in the Y direction so that thewire 30 is locked. - In the present embodiment, the
wire 30 is held in a state where thetips 54 f of thelock pieces 54 a bite the wall surface 32 g of thecore 32. More particularly, thewire 30 is held in the state where thetips 54 f of thelock pieces 54 a bite the wall surface 32 g of thecore 32 along the circumference thereof. - The
tips 54 f of thelock pieces 54 a biting the wall surface 32 g of thecore 32 along the circumference thereof thus can lock and prevent thewire 30 from being shifted in the X direction (the axial direction of the wire 30) more reliably. - In the present embodiment, the
contact 50 is formed in such a manner as to be subject to metal press processing. The other ends 54 c of thelock pieces 54 a include theedges 54 g and edges 54 h, in which thesharper edges 54 g formed by the metal press processing in the punching direction are located toward thewire 30. As a result, thesharper edges 54 g bite the wall surface 32 g of the core 32 so as to lock thewire 30 more rigidly. In the present embodiment, the sharper edges obtained by the press processing serve as a member for biting the wall surface 32 g of the core 32 (a member for locking the wire 30). - The
tips 54 f of thelock pieces 54 a are provided withinclined portions 54 k on the other side in the Z direction (toward the opening 50 a: on the side where thewire 30 is inserted), and provided with an opening having a width increasing toward the opening 50 a when viewed in the X direction and defined by theinclined portions 54 k on both sides in the Y direction. The opening having a width increasing toward the opening 50 a and formed at therespective lock portions 54 facilitates the insertion of thewire 30 into thecontact 50. - As described above, according to the present embodiment, the guide portions for inserting the wire (the tapered openings each having a width increasing toward the opening 50 a) are formed in the
contact portions 53 on the other side in the Z direction (toward the opening 50 a: on the side where thewire 30 is inserted) and in thelock portions 54 on the other side in the Z direction (toward the opening 50 a: on the side where thewire 30 is inserted), so as to insert thewire 30 into thecontact 50 more easily. - The locked state of the
wire 30 with thelock pieces 54 a can be ensured as follows. - First, the
wire 30 is moved to thecontact 50 in the direction perpendicular to the axial direction (the wire extending direction) and inserted between therespective holding pieces 53 c and between thefirst lock pieces 54 d and thesecond lock pieces 54 e. The wall surface 32 g of thecore 32 of thewire 30 is then held by the holdingpieces 53 c and also held by thetips 54 f of thelock pieces 54 a. Once thewire 30 in the held state is pulled in the X direction (the axial direction of the wire 30), thetips 54 f of thelock pieces 54 a bite the wall surface 32 g of thecore 32. As a result, thewire 30 is locked with thelock pieces 54 a so that a movement of thewire 30 in the X direction (the axial direction of the wire 30) is restricted. - As described above, the
contact 50 in the present embodiment is provided with the opening 50 a on the side where thewire 30 is inserted, and provided with the movement regulation member (thebottom walls 51 and the connecting portion 52) 50 c on the side opposite to the insertion side of thewire 30. - Since the opening 50 a of the
contact 50 is entirely open to the side where thewire 30 is inserted, thewire 30 can be inserted into thecontact 50 at any point along the wire 30 (the excluding both ends). The opening 50 a is open in the direction vertical to one surface (onesurface 52 a) of themovement regulation member 50 c. Here, the opening 50 a is not necessarily open in the direction vertical to the one surface of the movement regulation member and may be open in the direction parallel to or lateral direction. - In the present embodiment, the
contact 50 is formed to have a symmetrical configuration (point symmetry in the plan view). As a result, the installation direction or the engaging direction is not restricted so as to increase usability. - In addition, a
space 55 is provided between therespective lock portions 54 located on both sides in the X direction, and theland portion 25 is housed in thespace 55. - The connector configured as described above is assembled as follows.
- First, the exposed
core 32 of thewire 30 is inserted into theinsertion hole 20 a of theplug housing 20 so as to be set to the state shown inFIG. 10( a) from the state shown inFIG. 8 . - Then, the
jigs 90 for flattening are inserted from both sides in the Z direction (in the direction of arrow “a” inFIG. 9( a)) to flatten thetip portion 32 a of the core 32 once so as to form the first flattenedportion 32 c (refer toFIG. 10( b)). Subsequently, thewire 30 is moved in the X direction so that the flattened surface of the first flattenedportion 32 comes into contact with the deep surface (the surface toward the upper wall 22) 21 d of thenotch 21 c (refer toFIG. 10( c)). - Thereafter, the
pressing portions 91 of thejigs 90 for flattening are inserted from both sides in the Z direction (in the direction of arrow “a” inFIG. 9( a)) to flatten thetip portion 32 a of the core 32 so as to form the second flattenedportion 32 d adjacent to the first flattenedportion 32 c (refer toFIG. 10( d)). - The flattened
portion 32 b including the first flattenedportion 32 c and the second flattenedportion 32 d is thus formed and comes into contact (is locked) with thelateral wall portion 23 b when thewire 30 inserted into theplug housing 20 is moved in the removing direction, so as to prevent thewire 30 from coming off theplug housing 20. Further, theflat surface 32 e of the flattenedportion 32 b comes into contact (is locked) with the deep surface (the surface toward the upper wall 22) 21 d of thenotch 21 c so as to prevent the rotation of thewire 30. - Accordingly, the
wired housing 40 is formed as shown inFIG. 9( a). Thewire 30 is housed and fixed (attached) in theplug housing 20 without using thecontact 50. Theplug housing 20 holds thewire 30 housed in thehousing portion 24 in a manner such that thecore 32 is exposed to the outside via theopening 24 when viewed in the open direction of the opening 24 a (the Z direction). - Subsequently, the installation member (at least one of the
bottom walls 51 and the connecting portion 52) is connected to theboard 60 by soldering or the like so as to install (connect) thecontact 50 to theboard 60. - In a state where the wired
housing 40 and thecontact 50 attached to theboard 60 are placed in a manner such that theplug housing 20 on theopening 24 side is opposed to thecontact portions 53 of thecontact 50 on the opening side, thecontact portions 53 are housed in theopening 24, and the exposedcore 32 of thewire 30 is inserted into thecontact portions 53 from the opening side and held by the holdingpieces 53 c (refer toFIG. 18 ). When thecore 32 is inserted into thecontact portions 53 from the opening side, thecore 32 is pushed by the mount surfaces 26 a of themount portions 26 provided in theplug housing 20 on the side opposite to the contact portions 53 (on the upper side inFIG. 18 ) so as to prevent the core 32 from bending. - The
tips 54 f of thelock pieces 54 a of thelock portions 54 hold the wall surface 32 g of the core 32 (refer toFIG. 19 ). Once thewire 30 is pulled in the X direction (the axial direction of the wire 30), thetips 54 f of thelock pieces 54 a bite the wall surface 32 g of the core 32 so that thewire 30 is locked with thelock pieces 54 a. Theland 25 is thus housed in thespace 55. - Accordingly, the
board 60 and thewire 30 are electrically connected to each other. - Next, application examples of the
connector 10 according to the present embodiment are explained below. Note that the following explanations are examples, and the usage manner of theconnector 10 is not limited to those examples described below. - First, as shown in
FIG. 20 , theconnector 10 according to the present embodiment can be used for electrically connecting boards (LED boards) 60 equipped withLEDs 61 to each other.FIG. 20 discloses a case where fourboards 60 are connected in series. Theleftmost board 60 inFIG. 20 is further equipped with apower supply circuit 62 in addition to theLEDs 61. The other threeboards 60 are not equipped with thepower supply circuit 62 but only equipped with theLEDs 61. Theleftmost board 60 equipped with thepower supply circuit 62 shown inFIG. 20 is provided with the board-to-wire connectors 10 attached on the left side of theboard 60. Twocontacts 50 are installed (connected) in parallel in the width direction (in the vertical direction inFIG. 20 ) on the left side of theleftmost board 60 inFIG. 20 . The twocontacts 50 are each housed in thehousing portion 24 of theplug housing 20 fixed (attached) to one side of thewire 30 so as to come into contact with thewire 30. As a result, thewires 30 and theboard 60 are electrically connected to each other. The other side of eachwire 30 is electrically connected to an external power source (not shown in the drawing) so as to be supplied with power. Theleftmost board 60 inFIG. 20 is further provided, on the right side, with twocontacts 50 installed (connected) in parallel in the width direction (in the vertical direction inFIG. 20 ). Theother boards 60 of the fourboards 60 are also provided with twocontacts 50 installed (connected) in parallel in the width direction (in the vertical direction inFIG. 20 ) toward the respectiveadjacent boards 60. - These portions in the boards 60 (the right side of the
leftmost board 60 and the both right and left sides of each of the other three boards 60) are attached with theconnectors 10 connected to thewires 30 on both sides (board-to-board type connectors 10). - More particularly, the
contacts 50 installed on the right side of theleftmost board 60 inFIG. 20 and thecontacts 50 installed on the left side of thesecond board 60 from the left inFIG. 20 are housed in therespective housing portions 24 of theplug housings 20 so as to come into contact with thewires 30. Thus, the board-to-board type connectors 10 are attached and extend across theleftmost board 60 inFIG. 20 and thesecond board 60 from the left inFIG. 20 in a manner such that the respective ends of thewires 30 fixed to therespective plug housings 20 are fitted (inserted) into thecontacts 50 installed on the right side of theleftmost board 60 inFIG. 20 and thecontacts 50 installed on the left side of thesecond board 60 from the left inFIG. 20 . As a result, theleftmost board 60 inFIG. 20 and thesecond board 60 from the left inFIG. 20 are electrically connected to each other. The connection between thesecond board 60 from the left inFIG. 20 and thesecond board 60 from the right inFIG. 20 , and the connection between therightmost board 60 inFIG. 20 and thesecond board 60 from the right inFIG. 20 are performed in the same manner as described above. The twocontacts 50 vertically arranged and installed on the right side of therightmost board 60 inFIG. 20 are each housed in thehousing portion 24 of theplug housing 20 so as to come into contact with thewire 30. The twocontacts 50 vertically arranged and installed on the right side of therightmost board 60 inFIG. 20 is thus short-circuited. - The use of such board-to-
board type connectors 10 can eliminate the use of a jumper pin for short-circuiting, and eliminate the use of a board to which a jumper pin can be attached. In other words, short-circuiting can be executed by any of theboards 60 shown inFIG. 20 so as to increase versatility. - As described above, the board-to-
wire type connectors 10 and the board-to-board type connectors 10 are used so as to electrically connect therespective boards 60 to each other and turn on theLEDs 61 installed on theboards 60. The use of theconnectors 10 described above further facilitates the attachment of thewires 30 to thecontacts 50. In addition, since the respective connectors 10 (the board-to-wire type connectors 10 and the board-to-board type connectors 10) are low-profile connectors, the attachment of theconnectors 10 to theboards 60 can be achieved without blocking emission of theLEDs 61. - As shown in
FIG. 21 , theconnector 10, floatingconnectors 63 and a short-circuit connector 64 may be used so as to connect the boards (LED boards) 60 with which theLEDs 61 are equipped.FIG. 21 also discloses the case where fourboards 60 are connected in series. Theleftmost board 60 inFIG. 21 is equipped with thepower supply circuit 62 in addition to theLEDs 61. The other threeboards 60 are not equipped with thepower supply circuit 62 but only equipped with theLEDs 61. Theleftmost board 60 equipped with thepower supply circuit 62 shown inFIG. 21 is provided on the left side with theconnector 10 according to the present embodiment that is electrically connected to an external power source (not shown in the drawing) so as to be supplied with power. Theleftmost board 60 and the twoboards connectors 63. The floatingconnectors 63 are used in order to absorb displacement and electrically connect the respective boards to each other. - The
rightmost board 60 inFIG. 21 is provided with the short-circuit connector 64 on the right side thereof. - As described above, the
connector 10, the floatingconnectors 63 and the short-circuit connector 64 are used so as to electrically connect therespective boards 60 to each other and turn on theLEDs 61 installed on theboards 60 as in the case described above. - When the respective connectors (the
connector 10, the floatingconnectors 63 and the short-circuit connector 64) used are low-profile connectors, the attachment of the connectors to theboards 60 can be achieved without blocking emission of theLEDs 61. - As shown in
FIG. 22 , theconnector 10 according to the present embodiment may be used for anLED bulb 70. More particularly, theconnector 10 can be used for electrically connecting the board (LED board) 60 placed in a glassspherical body 71 of theLED bulb 70 and equipped with theLEDs 61 to the board (power source board) 60 equipped with thepower supply circuit 62. - In
FIG. 22 , the board (the LED board) 60 equipped with theLEDs 61 are substantially horizontally placed in the glassspherical body 71 in a manner such that theboard 60 on the side where theLEDs 61 is installed faces upward. In addition, the board (the power supply board) 60 equipped with thepower supply circuit 62 is substantially horizontally placed below the board (the LED board) 60. Here, the member indicated byreference numeral 65 is a circuit component such as a capacitor. - In
FIG. 22 , the board (the LED board) 60 and the board (the power supply board) 60 are electrically connected to each other via the board-to-wire type connector 10. More particularly, thecontact 50 installed on the board (the LED board) 60 is housed in thehousing portion 24 of theplug housing 20 fixed (attached) to one side of thewire 30 so that thecontact 50 is connected to thewire 30. Thewire 30 and the board (the LED board) 60 are thus electrically connected to each other. The exposed part of the core 32 on the other side of thewire 30 is soldered onto the board (the power source board) 60 so that thewire 30 and the board (the power source board) 60 are electrically connected to each other. The board (the LED board) 60 and the board (the power supply board) 60 are thus electrically connected to each other via the board-to-wire type connector 10 so as to turn on theLEDs 61. Alternatively, theconnector 10 of the board-to-wire type connector 10 may be attached to the board (the power supply board) 60, and the other side of thewire 30 may be soldered onto the board (the LED board) 60. - The board (the power supply board) 60 is also electrically connected to a
base 72 via a lead (not shown in the drawing). Thebase 72 is attached to a socket (not shown in the drawing) electrically connected to an external power source so as to supply power to theLEDs 61 and turn on theLEDs 61. - As shown in
FIG. 23 , the board (the power supply board) 60 may be placed substantially vertically below the board (the LED board) 60. InFIG. 23 , the board-to-wire type connector 10 is used to connect the board (the LED board) 60 to the board (the power supply board) 60 as in the case described above. - In the configurations shown in
FIG. 22 andFIG. 23 , the board-to-board type connector 10 in which thewire 30 is provided with theconnectors 10 on both sides may be used. - When the board-to-
wire type connector 10 or the board-to-board type connector 10 is a low-profile connector in the configuration shown inFIG. 22 orFIG. 23 , the attachment of theconnector 10 to theboards 60 can be achieved without blocking emission of theLEDs 61. - As described above, according to the present embodiment, the
wire 30 is moved in the perpendicular direction (the Z direction) to the axial direction (the wire extending direction: the X direction) so as to be inserted into thecontact 50. Therefore, thewire 30 can be prevented from being bent when thewire 30 is inserted into thecontact 50, which further facilitates the attachment of thewire 30 to thecontact 50. - In the embodiment, the
connector 10 according to the present embodiment includes the lock portions (movement restriction member) 54 having thelock pieces 54 a holding thewire 30 in the state thewire 30 is in contact with thecontact portions 53. Therefore, thewire 30 can be locked with thelock portions 54 in the state where thewire 30 is attached to thecontact 50. Accordingly, thewire 30 can be prevented from coming off thecontact 50 more reliably. Particularly, the lock portions (the movement restriction member) 54 can restrict a movement of thewire 30 in the wire extending direction (the X direction), so that thewire 30 can be prevented from being bent or coming off theplug housing 20 when thewire 30 is pulled outward from theplug housing 20 in the inserting-removing direction (the X direction) for some reasons such as because of other members being stuck. - In the present embodiment, the
tips 54 f of thelock pieces 54 a hold thewire 30 while biting the wall surface 32 g of thecore 32. More particularly, thetips 54 f of thelock pieces 54 a hold thewire 30 while biting the wall surface 32 g of thecore 32 along the circumference thereof. Therefore, thetips 54 f of thelock pieces 54 a biting the wall surface 32 g of thecore 32 along the circumference thereof can lock and prevent thewire 30 from being shifted in the X direction (the axial direction of the wire 30). - In the present embodiment, the
wire 30 is housed and fixed (attached) in theplug housing 20 without using thecontact 50. Theplug housing 20 houses the core 32 (the wire 30) in a manner such that thecore 32 is exposed to the outside via theopening 24 when viewed in the open direction of the opening 24 a (the Z direction). In other words, thecore 32 of thewire 30 is directly attached to thecontact portions 53 of thecontact 50. Since thewire 30 is detachable from thecontact 50, thecore 32 of thewire 30 can be removed from thecontact portions 53 of thecontact 50 easily, and the engagement between thewire 30 and thecontact 50 can be released easily. - The
contact 50 further includes themovement regulation member 50 c for regulating a movement of thewire 30 in the Z direction in the state where thewire 30 is in contact with thecontact portions 53. Themovement regulation member 50 c provided in thecontact 50 can eliminate an additional member for preventing the contact state between thewire 30 and thecontact portions 53 from being released because of a movement of thewire 30 on thecontact 50 in the Z direction. Thus, thewire 30 can be prevented from coming off thecontact 50 because of excessive insertion of thewire 30 with no additional member used. Therefore, even when theplug housing 20 is used, theplug housing 20 is not necessarily formed into a complicated shape, and the configuration thereof can be further simplified so as to reduce manufacturing costs. - According to the present embodiment, the
contact portions 53 include theouter pieces 53 a as the first side wall portions located on both sides in the Y direction (the width direction) when viewed in the X direction, and the two holding pieces (at least one second side wall portion) 53 c located between theouter pieces 53 a. - The two holding
pieces 53 c (at least one second side wall portion) are formed in an elastically deformable manner so that thewire 30 is held on both sides in the Y direction (at least one side in the Y direction) by the holdingpieces 53 c elastically deformable in the Y direction. - Therefore, when the
wire 30 is pulled in the Y direction for some reasons such as because of other members being stuck, force in the Y direction applied to thecontact 50 can be absorbed by elastic deformation of the holdingpieces 53 c. Accordingly, the outer pieces (the first side wall portions) 53 a of thecontact 50 can be prevented from receiving the force, and thecontact 50 installed on theboard 60 can be prevented from being removed. Such a configuration can increase the rigidity of the outer pieces (the first side wall portions) 53 a of thecontact 50 and prevent thewire 30 from coming off thecontact 50 so as to prevent the external shape of thecontact 50 from being deformed. Thus, when theplug housing 20 is used, thecontact 50 can be prevented from failing to be housed in thehousing portion 24 of theplug housing 20 because of deformation of thecontact 50. - According to the present embodiment, the two (plural) lock portions (movement restriction member) 54 are provided and symmetrically located when viewed in the Z direction (the perpendicular direction). Therefore, the
contact 50 can lock thewire 30 at two points (plural points) more evenly and stably. - According to the present embodiment, the
contact 50 is formed in a manner such that a metal plate is subjected to metal processing (pressing), which facilitates the process of formation of thecontact 50. The sharper edges 54 g formed by the metal press processing in the punching direction are located toward thewire 30. Thus, the strength to lock thewire 30 with thelock portions 54 can be increased more easily by use of the characteristics of the metal press processing. - The lock portions (movement restriction member) 54 include locking pieces for locking the
wire 30 in the state where thewire 30 is in contact with thecontact portions 53. The locking pieces include thelock pieces 54 for holding thewire 30 in contact with thecontact portions 53 so as to lock thewire 30 with a simpler configuration and form the lock portions (movement restriction member) 54 more easily. - According to the present embodiment, the core 32 (the wire 30) includes the flattened
portion 32 b formed in such a manner as to flatten thetip portion 32 a. Theplug housing 20 includes the lockingportion 20 b for locking the flattenedportion 32 b of the core 32 (the wire 30). This configuration can fix thewire 30 to theplug housing 20 with the simple process of flattening thetip portion 32 a of the core 32 (the wire 30). - According to the present embodiment, the
plug housing 20 includes thehousing portion 24 for housing thewire 30, the opening 24 a communicating with thehousing portion 24 in such a manner as to be open in the perpendicular direction (the Z direction) perpendicular to the wire extending direction (the X direction) in which thewire 30 extends so that thewire 30 housed in thehousing portion 24 is exposed to the outside via theopening 24 a when viewed in the open direction of the opening 24 a (the Z direction), and the locking portion (the holding portion) 20 b for holding thewire 30 housed in thehousing portion 24. Thehousing portion 24 can receive thecontact 50 connected to the board (the member to be connected) 60 via theopening 24 a. Thus, the direct electrical connection between thewire 30 attached to theplug housing 20 having the configuration described above and thecontact 50 can be achieved without depending on theplug housing 20, which further facilitates the electrical connection between thewire 30 and the board (the member to be connected) 60. - According to the present embodiment, the
plug housing 20 is provided with the through-hole 22 b open on one of the wall surfaces surrounding the lockingportion 20 b so that thetip portion 32 a (the wire 30) of thecore 32 is exposed to the outside via the through-hole 22 b. The through-hole 22 b enables thetip portion 32 a of the core 32 (the wire 30) to be flattened after thetip portion 32 a of the core 32 (the wire 30) is inserted into the lockingportion 20 b of theplug housing 20 so as to further facilitate the attachment of thewire 30 to theplug housing 20. - According to the present embodiment, the through-holes are provided on both sides in the Z direction (the wall surfaces opposed to each other) of the wall surfaces surrounding the locking
portion 20 b so that the lockingportion 20 b penetrates in the Z direction. Thus, the through-holes enable thepressing portions 91 of thejigs 90 for flattening to be inserted from both sides in the Z direction so as to further facilitate the process of flattening thetip portion 32 a of the core 32 (the wire 30). - According to the present embodiment, the
wire 30 includes the core 32 composed of a solid wire. Therefore, thewire 30 is suitable for laying for longer distances (such as 10 m or longer) with lower cost than the case where thecore 32 is composed of a stranded wire, so as to ensure stable communication while being hardly influenced by noise. - A
connector 10A according to the present embodiment has a configuration substantially similar to the first embodiment. - The
connector 10A according to the present embodiment also includes thecontact 50 connected to theboard 60. Thewire 30 is connected to thecontact 50 so that thewire 30 is electrically connected to theboard 60. - The
connector 10A according to the present embodiment differs from theconnector 10 according to the first embodiment in that, as shown inFIG. 24 andFIG. 25 , thecore 32 of thewire 30 is directly brought into contact with thecontact portions 53 of thecontact 50 without theplug housing 20 used. - As shown in
FIG. 26 , the present embodiment may be applied to a board-to-wire type connector so that thewire 30 may be directly fitted (inserted) on one side to thecontact portions 53 of thecontact 50 without theplug housing 20 used. - The present embodiment described above can also achieve the operations and effects similar to the first embodiment.
- According to the present embodiment, the
core 32 of thewire 30 is directly brought into contact with thecontact portions 53 of thecontact 50 without theplug housing 20 used. This configuration can simplify theconnector 10A and reduce the weight thereof. - Particularly, the
movement regulation member 50 c formed in thecontact 50 can prevent thewire 30 from coming off thecontact 50 caused by excessive insertion of thewire 30 without using other members such as a housing. Thus, reliability of connection between thecontact 50 and thewire 30 can be improved without using other members such as a housing. - Further, the
connector 10A according to the present embodiment is applicable to the application examples shown inFIG. 20 toFIG. 23 . - Next, modified examples of the
wire 30 are explained below. - The
wire 30 shown inFIG. 27 includes a core 32B composed of a stranded wire. Thewire 30 shown inFIG. 27 is a crossover cable in which seven thin copper wires (φ0.2) are stranded. The core 32B composed of the stranded wire is covered with the insulating coveringmember 31 so as to form thewire 30. Thewire 30 is inserted into the insertion hole 30 a in a state where part of the coveringmember 31 on the tip side is removed to expose the core 32B to the outside. The use of the crossover cable facilitates the insertion of the core 32B composed of the stranded wire into theinsertion hole 20 a (theinsertion recess 20 c, the through-hole 25 c, the lockingportion 20 b) of theplug housing 20. - This
wire 30 is more flexible than thewire 30 using the solid wire as a core so as to facilitate the laying operation. - The
wire 30 shown inFIG. 28 is a straight cable including acore 32C composed of a stranded wire. - More particularly, as shown in
FIG. 28 , seven thin copper wires (φ0.2) are aligned straight. Thecore 32C composed of the stranded wire is covered with the insulating coveringmember 31 so as to form thewire 30. Thewire 30 is inserted into the insertion hole 30 a in the state where part of the coveringmember 31 on the tip side is removed to expose thecore 32C to the outside. The use of the straight stranded wire described above may cause the copper wires of the core 32C to spread out in directions so that it is difficult to insert the wire into theinsertion hole 20 a. Thus, when the coveringmember 31 of thewire 30 is removed to expose thecore 32C to the outside, thecore 32C is preferably subjected to pretreatment such as soldering. Such pretreatment facilitates the insertion of thecore 32C composed of the stranded wire into theinsertion hole 20 a (theinsertion recess 20 c, the through-hole 25 c, the lockingportion 20 b) of theplug housing 20. - The
wire 30 includes thecore 32C composed of the stranded wire. Therefore, thewire 30 is more flexible than thewire 30 using the solid wire as a core so as to facilitate the laying operation. -
FIG. 29 illustrates a configuration in which thewire 30 is composed of acoaxial cable 32D. InFIG. 29 , an internal conductor 33 (core) composed of a stranded wire is covered with aninsulator 34, and anexternal conductor 35 formed on the outside of theinsulator 34 is covered with the coveringmember 31. Thecoaxial cable 32D is flexible so as to facilitate the laying operation and prevent external leakage of electromagnetic waves. - Although
FIG. 29 illustrates the case where the internal conductor 33 (the core) is composed of the stranded wire, the internal conductor 33 (the core) composed of a solid wire may be used. - Next, modified examples of the contact are explained below.
- The
contact 50 shown inFIG. 30 includes the drop-off prevention portions formed in the lock pieces (the locking pieces) 54 a of the lock portions (the movement restriction member) 54 for covering at least part of thewire 30 on the other side in the Z direction while being in contact with the contact portions 53 (toward the opening 50 a in the state where thewire 30 is in contact with the contact portions 53). - More particularly, the
tips 54 f of the lock pieces (the locking pieces) 54 a are provided, on theopening 50 a side, withprojections 54 i projecting in the Y direction and the X direction. The gap between therespective projections 54 i on both sides in the Y direction is smaller than the diameter of thewire 30. - The
projections 54 i shown inFIG. 30 are each formed substantially into a trapezoid having a thickness decreasing toward the tip thereof when viewed from the side surface (when viewed in the Y direction). Therefore, inclined surfaces of theprojections 54 i toward the opening 50 a can serve as a guide when thewire 30 is inserted so as to prevent the insertion of thewire 30 into thecontact 50 from being blocked by theprojections 54 i. - The
projections 54 i having such a configuration can prevent thewire 30 from moving in the direction opposite to the direction in which thewire 30 is attached (the direction in which thewire 30 is inserted) and prevent thewire 30 from coming off. Further, since thewire 30 is inserted into thecontact 50 by climbing over the drop-off prevention portions protruding inward in the Y direction, a feeling of clicking can be ensured at the time of insertion of thewire 30 so that the connection of thewire 30 can be confirmed easily. AlthoughFIG. 30 illustrates the case where the drop-off prevention portions are formed in thecontact portions 53 and the lock portions (the movement restriction member) 54 to cover at least part of thewire 30 on the other side in the Z direction while being in contact with the contact portions 53 (toward the opening 50 a in the state where thewire 30 is in contact with the contact portions 53), the drop-off prevention portions may be formed only in the lock portions (the movement restriction member) 54, instead of being formed in both thecontact portions 53 and the lock portions (the movement restriction member) 54. - The
contact 50 described above can also achieve substantially the same operations and effects as those in the first and second embodiments. Further, thecontact 50 shown inFIG. 30 has a configuration in which the locking portions of thelock pieces 54 a at which thewire 30 is locked (theedges 54 g) and the holdingpieces 53 c of thecontact portions 53 are arranged approximately at even intervals in the X direction. Theedges 54 g and the holdingpieces 53 c are portions by which the insertion of thewire 30 into thecontact 50 is blocked (portions at which thewire 30 is hardly inserted if greater force is not applied thereto than that applied to other portions in the contact) when thewire 30 is inserted into thecontact 50 while two parts of thewire 30 on the outside of thecontact 50 in the X direction are gripped. Thus, the blocking portions are arranged approximately at even intervals in the X direction in thecontact 50 shown inFIG. 30 . As a result, the force applied to thewire 30 can be dispersed evenly in the X direction so as to be prevented from being partly applied to thewire 30 when thewire 30 is inserted into thecontact 50. - The
contact 50 shown inFIG. 31 has a configuration, as in the case of the contact shown inFIG. 30 , in which the drop-off prevention portions are formed in the lock pieces (the locking pieces) 54 a of the lock portions (the movement restriction member) 54 for covering at least part of thewire 30 on the other side in the Z direction while being in contact with the contact portions 53 (toward the opening 50 a in the state where thewire 30 is in contact with the contact portions 53). - Further, the
contact 50 shown inFIG. 31 includesrecesses 51 c formed on thebottom walls 51 serving as the installation member on the outer side in the X direction. In thecontact 50 shown inFIG. 31 , therecesses 51 c are formed at the edges of thebottom walls 51 in the X direction. More particularly, therecesses 51 c are each formed in a manner such that a part of the edge of thebottom wall 51 in the X direction is notched into an arc shape. Therecesses 51 c are each formed to penetrate in the Z direction so that the board (the member to be connected) 60 is exposed to the outside when viewed in the Z direction (viewed from one side of the installation member). Here, therecesses 51 c may each be formed in a manner such that the entire edge of thebottom wall 51 in the X direction is notched into an arc shape, instead of being formed in a manner such that a part of the edge of thebottom wall 51 in the X direction is notched. Alternatively, the recesses may each be formed at an edge of the installation member in the Y direction. Further, the recesses are not limited to the arc shape and may be any shapes, and the number of the recesses may also be determined as appropriate. - The
recesses 51 c can each serve as a soldering confirmation portion at which a solder fillet is formed. In particular, therecesses 51 c are formed on thebottom walls 51 c so that a state of solder wetting can be confirmed with the solder fillets formed at therecesses 51 c when thecontact 50 is soldered onto the board (the member to be connected) 60. Therecesses 51 c thus contribute to easily determining whether the board (the member to be connected) 60 and thecontact 50 are connected (installed) appropriately, and further improving the reliability of connection (installation) between the board (the member to be connected) 60 and thecontact 50. AlthoughFIG. 31 illustrates the case where thebottom walls 51 compose at least part of the installation member provided with therecesses 51 c serving as a soldering confirmation portion, the connectingportion 52 may serve as the installation member where the soldering confirmation portion is formed. The soldering confirmation portion is not limited to the shape notched into a U-shape and may be various shapes such as a through-hole penetrating thebottom walls 51 in the thickness direction (the Z direction) formed adjacent to the edges of thebottom walls 51. Further, the position and the number of the solder confirmation portion formed may be determined as appropriate. For example, the recesses or through holes may be formed at positions where soldering installation is performed, instead of the edges of thebottom walls 51, so as to serve as the soldering confirmation portion. - The
contact 50 shown inFIG. 32 has a configuration in which the connectingportion 52 is formed into a rectangular shape, and the lock pieces (the locking pieces) 54 a of the respective lock portions (the movement restriction member) 54 are formed in a manner such that thetips 54 f extend outward in the X direction. Thelock pieces 54 a of the twolock portions 54 having the shape described above also extend in opposite directions. - Thus, the
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 30 . - In the contact shown in
FIG. 32 , the distance between the locking portions of thelock pieces 54 a at which thewire 30 is locked (theedges 54 g) and the holdingpieces 53 c of thecontact portions 53 is smaller than that in thecontact 50 shown inFIG. 30 . Therefore, thewire 30 can be inserted more easily when the insertion of thewire 30 into onecontact portion 53 and the insertion of thewire 30 into thelock portion 54 adjacent to thecontact portion 53 are made simultaneously. For example, thecontact 50 shown inFIG. 30 is provided with the four blocking portions by which the insertion of thewire 30 into thecontact 50 is blocked. On the other hand, thecontact 50 shown inFIG. 32 is provided with approximately two blocking portions. Thus, thecontact 30 can be prevented from being bent upward (prevented from being inserted into thecontact portions 53 located on the outer side in the X direction while thewire 30 is not inserted into thelock portions 54 located on the inner side in the X direction) when thewire 30 is inserted into thecontact 50 while two parts of thewire 30 on the outside of thecontact 50 in the X direction are gripped. Accordingly, the operability of insertion of thewire 30 into thecontact 50 can be further improved. - The
contact 50 shown inFIG. 33 has a configuration in which the connectingportion 52 is formed into a rectangular shape, and thecontact portions 53 are located on the inner side in the X direction and the lock portions (the movement restriction member) 54 are located on the outer side in the X direction. Further, the lock pieces (the locking pieces) 54 a of the respective lock portions (the movement restriction member) 54 are formed in a manner such that thetips 54 f extend inward in the X direction. - Thus, the
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 32 . - Further, the
contact 50 shown inFIG. 33 is provided with the two blocking portions closer to each other at which the insertion of thewire 30 into thecontact 50 is blocked, in which the one ends 54 b of the lock portions 54 (the sides on which thewire 30 is not locked in the lock portions 54) are located on both sides of thecontact 50 in the X direction. Thus, thecontact 30 can more reliably be prevented from being bent upward (prevented from being inserted into thecontact portions 53 located on the outer side in the X direction while thewire 30 is not inserted into thelock portions 54 located on the inner side in the X direction) when thewire 30 is inserted into thecontact 50 while two parts of thewire 30 on the outside of thecontact 50 in the X direction are gripped. Further, since the width of thecontact 50 in the Y direction is larger on both sides in the X direction than the diameter of thewire 30, thewire 30 can be shifted in the Y direction on both sides of thecontact 50 in the X direction. Therefore, thewire 30 can be bent in the Y direction without decreasing the radius of curvature of thewire 30 adjacent to thecontact 50. Accordingly, thewire 30 can be bent in the Y direction at the position closer to thecontact 50 so as to further expand the possibility of positioning of thecontact 50 installed on the board (member to be connected) 60 (the possibility of arrangement of the contact 50). - The
contact 50 shown inFIG. 34 has a configuration in which the connectingportion 52 is formed into a rectangular shape, and thecontact portions 53 are located on the inner side in the X direction and thelock portions 54 are located on the outer side in the X direction. Further, the lock pieces (locking pieces) 54 a of therespective lock portions 54 are formed in a manner such that thetips 54 f extend outward in the X direction. - Thus, the
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 30 . - Further, in the
contact 50 shown inFIG. 34 , the locking portions of thelock pieces 54 a at which thewire 30 is locked (theedges 54 g) are located on both sides of thecontact 50 in the X direction. Therefore, thewire 30 locked on both sides of thecontact 50 in the X direction and placed in thecontact 50 can be prevented from being bent. - The
contact 50 shown inFIG. 34 includes theedges 54 g of thelock pieces 54 a located on both sides of thecontact 50 in the X direction where it is relatively difficult to insert thewire 30, and thecontact portions 53 located on the inner side in the X direction where thewire 30 is relatively easily inserted. This configuration leads thecontact 50 to have four blocking portions at which the insertion of thewire 30 into thecontact 50 is blocked. However, the blocking portions located on the inner side in the X direction, among the four blocking portions at which the insertion of thewire 30 into thecontact 50 is blocked, have a configuration that enables thewire 30 to be relatively easily inserted into thecontact 50. Thus, thecontact 30 can relatively be prevented from being bent upward (prevented from being inserted into thecontact portions 53 located on the outer side in the X direction while thewire 30 is not inserted into thelock portions 54 located on the inner side in the X direction) when thewire 30 is inserted into thecontact 50 while two parts of thewire 30 on the outside of thecontact 50 in the X direction are gripped. - The
contact 50 shown inFIG. 35 has a configuration in which the connectingportion 52 is formed into a rectangular shape. Therespective contact portions 53 are provided with the contact pieces only on one side in the Y direction. More particularly, thecontact portions 53 each include theouter piece 53 a extending upward on one side of eachbottom wall 51 in the Y direction, the elastically deformable inner piece (the contact piece) 53 b integrated with theouter piece 53 a, and the elastically deformable holding piece (the contact piece) 53 c for holding thecore 32 of thewire 30. Further, thelock pieces 54 a of thelock portions 54 are also formed on one side of thebottom walls 51 in the Y direction. Thelock pieces 54 a provided only on one side in the Y direction are formed in a manner such that thetips 54 f extend inward in the X direction. - The other side of the
respective bottom walls 51 in the Y direction is provided with a substantially inverseU-shaped side wall 56. Theside walls 56 are formed on both sides in the X direction with the connectingportion 52 interposed therebetween, and formed in such a manner as to overlap with thecontact portions 53 and thelock portions 54 when viewed in the Y direction. Note that therespective side walls 56 are not necessarily formed into a plate shape to overlap with thecontact portions 53 and thelock portions 54 when viewed in the Y direction. For example, theside walls 56 may be provided with slits extending in the Z direction so as to be divided into plural parts in the X direction. Here, each slit is not required to be formed from the top to the bottom when viewed in the Y direction, and only part of (for example, only the upper half of) theside walls 56 may be provided with slits. The same explanations are also applied to theside walls 56 described below. - Therefore, the
wire 30 inserted into thecontact 50 is held between the holdingpieces 53 c located on one side in the Y direction and theside walls 56 located on the other side in the Y direction. In other words, thecontact 50 is provided with the holdingpieces 53 c, of the holdingpieces 53 c and theside walls 56, which are only formed to be elastically deformable in the Y direction (the width direction) so that thewire 30 is held at least on one side in the Y direction by the holdingpieces 53 c elastically deformable in the Y direction. Further, thewire 30 inserted into thecontact 50 is held between thelock pieces 54 a formed in an elastically deformable manner on one side in Y direction and theside walls 56 formed on the other side so that a movement of thewire 30 in the X direction is locked (restricted). - The
contact 50 shown inFIG. 35 having the configuration described above has line symmetry when viewed in the Z direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 30 . - Further, since the
contact 50 shown inFIG. 35 is provided with theside walls 56 having relatively high rigidity on the other side of thebottom walls 51 in the Y direction, thewire 30 inserted into thecontact 50 can be prevented from moving toward the other side in the Y direction due to theside walls 56. Thus, thecontact 50 shown inFIG. 35 is effectively used when thewire 30 should be prevented from moving to the other side in the Y direction (toward the side walls 56). Here, thewire 30 can be prevented from moving to the one side in the Y direction when thecontact 50 shown inFIG. 35 is reversed so that theside walls 56 are located on one side in the Y direction. Thus, theside walls 56 can be formed on either side to which thewire 30 should be prevented from moving so that the force applied to another side in the Y direction can be absorbed by the holdingpieces 53 c or thelock pieces 54 a so as to prevent the installation of thecontact 50 on theboard 60 from being released, while the movement of thewire 30 to one side is restricted by theside walls 56. - Although
FIG. 35 illustrates the case where the substantially inverseU-shaped side walls 56 each include afirst side wall 56 a located on the outer side in the Y direction (the width direction) when viewed in the X direction and asecond side wall 56 b located between thefirst side wall 56 a and the holdingpiece 53 c, the configuration of therespective side walls 56 is not limited thereto. For example, theside walls 56 may each be formed into merely a plate shape extending upward from thebottom wall 51. In other words, theside walls 56 may be provided only with thesecond side wall 56 b serving as thefirst side wall 56 a without being provided with thefirst side wall 56 a. In such a case, the contact includes only one holdingpiece 53 c serving as the second side wall between the side wall only having the first side wall and the outer piece (another first side wall) 53 a. Further, althoughFIG. 35 illustrates the case where theside walls 56 are provided on both sides in the X direction, theside wall 56 may be provided only on one side in the X direction. The same explanations are also applied to theside walls 56 described below. - The
contact 50 shown inFIG. 36 has a configuration in which thelock pieces 54 a extend in the direction opposite to that in thecontact 50 shown inFIG. 35 . - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 32 andFIG. 35 . - The
contact 50 shown inFIG. 37 has a configuration in which the contact pieces and the lock pieces are replaced with those in thecontact 50 shown inFIG. 35 in a manner such that the contact pieces are located on the inner side in the X direction, and the lock pieces are located on the outer side in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 33 andFIG. 35 . - The
contact 50 shown inFIG. 38 has a configuration in which the contact pieces and the lock pieces are replaced with those in thecontact 50 shown inFIG. 36 in a manner such that the contact pieces are located on the inner side in the X direction, and the lock pieces are located on the outer side in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 34 andFIG. 36 . - The
contact 50 shown inFIG. 39 has a configuration in which the contact pieces, thelock piece 54 a and theside wall 56 on one side in the X direction (on the lower left side inFIG. 35 ) in thecontact 50 shown inFIG. 35 are replaced with each other in the Y direction. Therefore, theside walls 56 on both sides in the X direction are arranged in the diagonal line when viewed in the Z direction. Thecontact portions 53 and thelock portions 54 on both sides in the X direction are also arranged in the diagonal line when viewed in the Z direction. Thecontact 50 shown inFIG. 39 has a symmetrical configuration (point symmetry in the plan view). - Since the
contact 50 shown inFIG. 39 having such a configuration is provided with the contact pieces elastically deformable in the Y direction placed on both sides in the Y direction, force applied to either side can be absorbed by elastic deformation of the contact pieces. - Further, since the
lock pieces 54 a elastically deformable in the Y direction are also placed on both sides in the Y direction, thelock pieces 54 a can bite thewire 30 on both sides in the Y direction. Accordingly, thewire 30 can be locked (restricted) more reliably. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 35 . - Further, since the
contact 50 shown inFIG. 39 is provided with theside walls 56 having relatively high rigidity on both sides in the Y direction, the movement of thewire 30 in the Y direction (the movement to one side in the Y direction and the movement to the other side in the Y direction) can be suppressed by therespective side walls 56, and the force applied in the Y direction (the force applied to one side in the Y direction and the force applied to the other side in the Y direction) can be absorbed by the holdingpieces 53 c or thelock pieces 54 a so as to prevent the installation of thecontact 50 on theboard 60 from being released. - The
contact 50 shown inFIG. 40 has a configuration in which the contact pieces, thelock piece 54 a and theside wall 56 on one side in the X direction (on the lower left side inFIG. 36 ) in thecontact 50 shown inFIG. 36 are replaced with each other in the Y direction. - Since the
contact 50 shown inFIG. 40 having such a configuration is provided with the contact pieces elastically deformable in the Y direction placed on both sides in the Y direction, force applied to either side can be absorbed by elastic deformation of the contact pieces. - Further, since the
lock pieces 54 a elastically deformable in the Y direction are also placed on both sides in the Y direction, thelock pieces 54 a can bite thewire 30 on both sides in the Y direction. Accordingly, thewire 30 can be locked (restricted) more reliably. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 36 andFIG. 39 . - The
contact 50 shown inFIG. 41 has a configuration in which the contact pieces, thelock piece 54 a and theside wall 56 on one side in the X direction (on the lower left side inFIG. 37 ) in thecontact 50 shown inFIG. 37 are replaced with each other in the Y direction. - Since the
contact 50 shown inFIG. 41 having such a configuration is provided with the contact pieces elastically deformable in the Y direction placed on both sides in the Y direction, force applied to either side can be absorbed by elastic deformation of the contact pieces. - Further, since the
lock pieces 54 a elastically deformable in the Y direction are also placed on both sides in the Y direction, thelock pieces 54 a can bite thewire 30 on both sides in the Y direction. Accordingly, thewire 30 can be locked (restricted) more reliably. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 37 andFIG. 39 . - The
contact 50 shown inFIG. 42 has a configuration in which the contact pieces, thelock piece 54 a and theside wall 56 on one side in the X direction (on the lower left side inFIG. 38 ) in thecontact 50 shown inFIG. 38 are replaced with each other in the Y direction. - Since the
contact 50 shown inFIG. 42 having such a configuration is provided with the contact pieces elastically deformable in the Y direction placed on both sides in the Y direction, force applied to either side can be absorbed by elastic deformation of the contact pieces. - Further, since the
lock pieces 54 a elastically deformable in the Y direction are also placed on both sides in the Y direction, thelock pieces 54 a can bite thewire 30 on both sides in the Y direction. Accordingly, thewire 30 can be locked (restricted) more reliably. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 38 andFIG. 39 . - The
contact 50 shown inFIG. 43 has a configuration in which onelock portion 54 is located between the two contact portions 53 (located in the middle in the X direction). Thelock portion 54 is provided with thefirst lock piece 54 d and thesecond lock piece 54 e, and the extending direction of thefirst lock piece 54 d is opposite to the extending direction of thesecond lock piece 54 e. - Therefore, the locking portion of the
first lock piece 54 d at which thewire 30 is locked (theedge 54 g) and the locking portion of thesecond lock piece 54 e at which thewire 30 is locked (theedge 54 g) are shifted in the X direction when viewed in the Y direction. Since the locking portions of thelock pieces 54 a at which thewire 30 is locked (theedges 54 g) are shifted from each other, the number of the locking portions at which thewire 30 is locked can be increased when viewed in the Y direction. Further, the locking portions of thelock pieces 54 a at which thewire 30 is locked (theedges 54 g) can be arranged in a manner such that the distance therebetween from the center of thecontact 50 in the X direction is substantially the same when viewed in the Y direction. In other words, thelock portion 54 can be prevented from being displaced to either side in the X direction. - The
contact 50 having the configuration described above can also achieve substantially the same operations and effects as those in the first and second embodiments. Further, a reduction in size of thecontact 50 in the X direction can be achieved. - The
contact 50 shown inFIG. 44 has a configuration in which onelock portion 54 is located between the two contact portions 53 (located in the middle in the X direction). Thelock portion 54 is provided with thefirst lock piece 54 d and thesecond lock piece 54 e, and the extending direction of thefirst lock piece 54 d is the same as the extending direction of thesecond lock piece 54 e. - Therefore, the locking portion of the
first lock piece 54 d at which thewire 30 is locked (theedge 54 g) and the locking portion of thesecond lock piece 54 e at which thewire 30 is locked (theedge 54 g) substantially coincide with each other when viewed in the Y direction. The locking portions of thelock pieces 54 a at which thewire 30 is locked (theedges 54 g) coinciding with each other can further increase the strength to lock thewire 30 with thelock portion 54. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Further, a reduction in size of thecontact 50 in the X direction can be achieved. - The
contact 50 shown inFIG. 45 has a configuration in which onecontact portion 53 and onelock portion 54 are aligned in the X direction. Thelock pieces 54 a extend in a manner such that thetips 54 f face thecontact portion 53 in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 32 . In addition, a further reduction in size of thecontact 50 in the X direction can be achieved. - The
contact 50 shown inFIG. 46 has a configuration in which onecontact portion 53 and onelock portion 54 are aligned in the X direction. Thelock pieces 54 a extend in a manner such that thetips 54 f are located on the opposite side of thecontact portion 53 in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 30 . In addition, a further reduction in size of thecontact 50 in the X direction can be achieved. - The
contact 50 shown inFIG. 47 has a configuration in which thecontact portions 53 are placed on both sides in the X direction, and the twolock portions 54 are placed between therespective contact portions 53. The connectingportion 52 is formed into a trapezoidal shape, and the lock pieces (locking pieces) 54 a of therespective lock portions 54 extend in a manner such that thetips 54 f face inward in the X direction. - The
respective contact portions 53 are bent outward on the tip side so that bases of the side walls cut and extending upward from both sides of thebottom walls 51 in the Y direction serve as contact pieces. In other words, the respective contact pieces of thecontact portions 53 on both sides in the Y direction are connected on one side opposite to theopening 50 a so as to be formed substantially into a U-shape. - When tip portions of the
outer pieces 53 a projecting in the Y direction are mounted on the board (the member to be connected) 60, the inner U-shaped portions (the holdingpieces 53 c connected to each other) can be elastically deformed in the Y direction (the width direction). Alternatively, the portions connecting the holdingpieces 53 c to each other may be mounted on the board (the member to be connected) 60. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 30 . In addition, theouter pieces 53 a are formed in a manner such that the tips of the holdingpieces 53 c bent upward from thebottom walls 51 are bent outward in the Y direction, which facilitates the manufacture of thecontact portions 53. - The
contact 50 shown inFIG. 48 has a configuration in which thelock pieces 54 a extend in the direction opposite to that in thecontact 50 shown inFIG. 47 . - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 32 andFIG. 47 . - The
contact 50 shown inFIG. 49 has a configuration in which thecontact portions 53 and thelock portions 54 are replaced with those in thecontact 50 shown inFIG. 48 in a manner such that thecontact portions 53 are located on the inner side in the X direction, and thelock portions 54 are located on the outer side in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 34 andFIG. 47 . - The
contact 50 shown inFIG. 50 has a configuration in which thecontact portions 53 and thelock portions 54 are replaced with those in thecontact 50 shown inFIG. 47 in a manner such that thecontact portions 53 are located on the inner side in the X direction, and thelock portions 54 are located on the outer side in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 33 andFIG. 47 . - The
contact 50 shown inFIG. 51 has a configuration in which the connectingportion 52 in thecontact 50 shown inFIG. 30 is provided with aprojection 52 d projecting toward the opening 50 a. Theprojection 52 d can be formed in a manner such that the connectingportion 52 is subjected to shearing processing. - As shown in
FIG. 52 , theprojection 52 d thus formed can prevent thewire 30 from moving to both sides in the Z direction in association with theprojections 54 i so as to hold thewire 30 in thecontact 50 more reliably. In addition, since the number of the contact points between thecontact 50 and thewire 30 increases, the electrical connection can be further stabilized. - The
contact 50 having the configuration described above can also achieve substantially the same operations and effects as those in the first and second embodiments. - The
contact 50 shown inFIG. 53 has a configuration in which the drop-off prevention portions for covering at least part of thewire 30 in contact with the contact portions 5 are formed at the lock pieces (the locking pieces) 54 a of the lock portions (the movement restriction member) 54 on one side in the Z direction (toward the movement regulation member), in addition to the other side in the Z direction. - More particularly, the
projections 54 i projecting in both the Y direction and the X direction are formed at thetips 54 f of the lock pieces (the locking pieces) 54 a toward the opening 50 a in a manner such that the gap between therespective projections 54 i located on both sides in the Y direction is smaller than the diameter of thewire 30. In addition,projections 54 j projecting in both the Y direction and the X direction are formed at thetips 54 f of the lock pieces (the locking pieces) 54 a toward the movement regulation member in a manner such that the gap between therespective projections 54 j located on both sides in the Y direction is smaller than the diameter of thewire 30. - As shown in
FIG. 54 , theprojections 54 i and theprojections 54 j of the lock pieces (the locking pieces) 54 a having such a configuration can prevent thewire 30 from moving to both sides in the Z direction so as to hold thewire 30 in thecontact 50 more reliably. In addition, since the number of the contact points between thecontact 50 and thewire 30 increases, the electrical connection can be further stabilized. - The
contact 50 having the configuration described above can also achieve substantially the same operations and effects as those in the first and second embodiments. - The
contact 50 shown inFIG. 55 has a configuration in which one lock portion (the movement restriction member) 54 is formed on thebottom wall 51 so that the lock portion (the movement restriction member) 54 also serves as thecontact portion 53, and thebottom wall 51 serves as the movement regulation member. In particular, once thewire 30 is inserted into thecontact 50 shown inFIG. 55 , the movement of thewire 30 in the X direction is restricted by thelock pieces 54 a of thelock portion 54, and thecontact 50 and thewire 30 is electrically connected to each other due to thelock pieces 54 a. - Accordingly, a reduction in size of the
contact 50 in the X direction can be achieved. Thecontact 50 having the configuration described above can also achieve substantially the same operations and effects as those in the first and second embodiments. - The
contact 50 shown inFIG. 56 has a configuration in which the two lock portions (the movement restriction member) 54 also serving as thecontact portions 53 are aligned in the X direction. Thelock pieces 54 a of the twolock portions 54 extend in the directions opposite to each other. InFIG. 56 , the lock pieces (the locking pieces) 54 a of therespective lock portions 54 extend in a manner such that therespective tips 54 f face inward in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 32 andFIG. 55 . Thecontact 50 shown inFIG. 56 comes into contact with and locks thewire 30 at two points when viewed in the Y direction. Accordingly, a reduction in size of thecontact 50 can be achieved, a movement of thewire 30 can be restricted, and reliability of connection between thecontact 50 and thewire 30 can be improved. - The
contact 50 shown inFIG. 57 has a configuration in which the two lock portions (the movement restriction member) 54 also serving as thecontact portions 53 are aligned in the X direction. Thelock pieces 54 a of the twolock portions 54 extend in the directions opposite to each other. InFIG. 57 , the lock pieces (the locking pieces) 54 a of therespective lock portions 54 extend in a manner such that therespective tips 54 f face outward in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 34 andFIG. 56 . - The
contact 50 shown inFIG. 58 has a configuration in which the two lock portions (the movement restriction member) 54 also serving as thecontact portions 53 are aligned in the X direction. Thelock pieces 54 a of the twolock portions 54 extend in the directions opposite to each other. InFIG. 58 , the lock pieces (the locking pieces) 54 a of therespective lock portions 54 extend in a manner such that therespective tips 54 f face inward in the X direction. In addition, therespective lock pieces 54 a located on the same side in the Y direction extend from oneside wall 57. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Therespective lock pieces 54 a located on the same side in the Y direction extend from thesame side wall 57 without being formed separately on the same side in the Y direction so as to further facilitate the formation of thecontact 50. - Here, the
respective side walls 57 are not necessarily formed into a plate when viewed in the Y direction. For example, theside walls 57 may be provided with slits extending in the Z direction so as to be divided into plural parts in the X direction. Each slit is not required to be formed from the top to the bottom when viewed in the Y direction, and only part of (for example, only the upper half of) theside walls 57 may be provided with slits. - Further, the
side wall 57 is not necessarily provided on both sides in the Y direction and may be provided only one side in the Y direction. - The
contact 50 shown inFIG. 59 has a configuration in which the respective threecontact portions 53 also serving as the lock portions (the movement restriction member) 54 are provided on both sides in the X direction with the connectingportion 52 interposed therebetween. In particular, the holdingpieces 53 c hold thewire 30 to electrically connect thewire 30 and thecontact 50, and at the same time, a movement of thewire 30 in the X direction is restricted (locked) due to frictional force of the holdingpieces 53 c. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Further, the configuration in which the contact portions having the same shape are aligned in the X direction has the advantage of facilitating the manufacture of thecontact 50. - Alternatively, the edges of the contact pieces of the contact portions 53 (the edges in the Z direction or the X direction) may be bent inward in the Y direction so as to lock the
wire 30 with the bent portions thus obtained. - Although
FIG. 59 illustrates the case where therespective contact portions 53 are individually provided with theouter pieces 53 a, theinner pieces 53 b and the holdingpieces 53 c, part of or the entireouter pieces 53 a may be connected at least between the twocontact portions 53. The same configuration may also be applied to theinner pieces 53 b or the holdingpieces 53 c. - The
contact 50 shown inFIG. 60 has a configuration in which thecontact portion 53 also serving as the lock portion (the movement restriction member) 54 is provided on each side in the X direction with the connectingportion 52 interposed therebetween. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 59 . - Alternatively, the edges of the contact pieces of the contact portions 53 (the edges in the Z direction or the X direction) may be bent inward in the Y direction so as to lock the
wire 30 with the bent portions thus obtained. - The
contact 50 shown inFIG. 61 has a configuration in which the sixcontact portions 53 also serving as the lock portions (the movement restriction member) 54 are aligned in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 59 . - Alternatively, the edges of the contact pieces of the contact portions 53 (the edges in the Z direction or the X direction) may be bent inward in the Y direction so as to lock the
wire 30 with the bent portions thus obtained. - Although
FIG. 61 illustrates the case where therespective contact portions 53 are individually provided with theouter pieces 53 a, theinner pieces 53 b and the holdingpieces 53 c, part of or the entireouter pieces 53 a may be connected at least between the twocontact portions 53. The same configuration may also be applied to theinner pieces 53 b or the holdingpieces 53 c. - The
contact 50 shown inFIG. 62 has a configuration in which only onecontact portion 53 also serving as the lock portion (the movement restriction member) 54 is provided. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 59 . - Alternatively, the edges of the contact pieces of the contact portion 53 (the edges in the Z direction or the X direction) may be bent inward in the Y direction so as to lock the
wire 30 with the bent portions thus obtained. - The
contact 50 shown inFIG. 63 has a configuration in which thecontact portions 53 are placed on both sides in the X direction, and the twolock portions 54 are placed between therespective contact portions 53. The connectingportion 52 is formed into a trapezoidal shape, and the lock pieces (the locking pieces) 54 a of therespective lock portions 54 extend in a manner such that thetips 54 f face inward in the X direction. - The
respective contact portions 53 are bent outward on the tip side so that bases of the side walls cut and extending upward from both sides of thebottom walls 51 in the Y direction serve as contact pieces (the holdingpieces 53 c). In other words, the respective contact pieces (the holdingpieces 53 c) of thecontact portions 53 on both sides in the Y direction are integrated with each other on one side opposite to theopening 50 a so as to be formed substantially into a U-shape. Further, the substantiallyU-shaped contact portions 53 are provided toward the opening 50 a with thecontact pieces 53 b gradually widening on both sides in the Y direction. Thecontact pieces 53 b having such a configuration enable thewire 30 to be inserted into thecontact 50 easily. - The
contact 50 is provided, to serve as thecontact pieces 53 b of thecontact portions 53, with the drop-off prevention portions 50 b for covering at least part of thewire 30 on the other side in the Z direction while being in contact with the contact portions 53 (on the opening side in the state where thewire 30 is in contact with the contact portions 53). - More particularly, the
respective contact pieces 53 b protrude inward in the Y direction in a manner such that the gap between therespective contact pieces 53 b located on both sides in the Y direction is smaller than the diameter of thewire 30. InFIG. 63 , thecontact pieces 53 b are curved greatly so as to protrude inward in the Y direction. - Accordingly, the
wire 30 can be prevented from moving in the direction opposite to the direction in which thewire 30 is attached (to the direction in which thewire 30 is inserted into the contact 50) and prevented from coming off thecontact 50. In addition, since thewire 30 is inserted into thecontact 50 by climbing over the drop-off prevention portions 50 b protruding inward in the Y direction, a feeling of clicking can be ensured at the time of insertion of thewire 30 so that the connection of thewire 30 can be confirmed easily. Here, thecontact portions 53 are not necessarily provided with thecontact pieces 53 b. In addition, thecontact pieces 53 b do not necessarily serve as the drop-off prevention portions 50 b. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontact 50 shown inFIG. 47 . In addition, thecontact 50 shown inFIG. 63 does not have a double-layer structure but is provided with a single side wall at the respective contact portions on each side in the Y direction when viewed in the X direction, which can facilitate the manufacture of thecontact 50 and achieve a simplification of the structure thereof. - The
contact 50 shown inFIG. 64 has a configuration in which thelock pieces 54 a extend in the direction opposite to that in thecontact 50 shown inFIG. 63 . - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 47 andFIG. 48 and thecontact 50 shown inFIG. 63 . - The
contact 50 shown inFIG. 65 has a configuration in which thecontact portions 53 and thelock portions 54 are replaced with those in thecontact 50 shown inFIG. 64 in a manner such that thecontact portions 53 are located on the inner side in the X direction, and thelock portions 54 are located on the outer side in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 47 andFIG. 49 and thecontact 50 shown inFIG. 63 . - The
contact 50 shown inFIG. 66 has a configuration in which thecontact portions 53 and thelock portions 54 are replaced with those in thecontact 50 shown inFIG. 63 in a manner such that thecontact portions 53 are located on the inner side in the X direction, and thelock portions 54 are located on the outer side in the X direction. - The
contact 50 having the configuration described above can achieve substantially the same operations and effects as those in the first and second embodiments. Thecontact 50 can also achieve substantially the same operations and effects as thecontacts 50 shown inFIG. 47 andFIG. 50 and thecontact 50 shown inFIG. 63 . - Although the present invention has been described above by reference to the preferred embodiments, the present invention is not limited to the descriptions thereof, and it will be apparent to those skilled in the art that various modifications and improvements can be made.
- For example, although the first embodiment exemplified the case where the tip of the wire is flattened after the wire is inserted into the locking portion of the housing, the wire may be inserted into the locking portion of the housing after the tip of the wire is flattened.
- When the board-to-board type connector is used, the wire may be attached with the housing only on one side and attached with the contact directly on the other side.
- Although the respective embodiments illustrated the contact portions provided with the opening on the side from which the wire is inserted, the contact portions not provided with the opening on the side from which the wire is inserted may be used.
